First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "CharCounter" (without the quotation marks) that gets two Strings called inputEntry and inputCharacter from the user after a displayed prompt. NOTES: Allow the inputEntry String to be one or more words of input. Verify that the inputCharacter String has a length of 1 and note these validations: If it doesn't, provide the user with suitable feedback and conclude the program.

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "CharCounter" (without the quotation marks) that gets two Strings called inputEntry and inputCharacter from the user after a displayed prompt. NOTES: Allow the inputEntry String to be one or more words of input. Verify that the inputCharacter String has a length of 1 and note these validations: If it doesn't, provide the user with suitable feedback and conclude the program. If the inputCharacter length is valid (i.e., it has a length of 1), use a while loop to check each position in the inputEntry variable and counts the number of times the character occurs. For example, if the inputEntry is "test" and the inputCharacter is "e" you would output: "There is 1 occurrence(s) of 'e' in test." Include multiple runs of this program using a variety of values for inputEntry and inputCharacter. Copy and paste all of…
*with psuedo code First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "WeightedAvgDataAnalyzer" (without the quotation marks), that does the following: This program is similar to the previous assignment - "WeightedAvgDropSmallest" - with a major difference that the inputs for the program will be read from a file and the output for this assignment should be written to a new file. The concept of application is as follows: The program will read numbers from a file - data.txt - that you will create, where the weight is a double (greater than 0.0 and less than or equal to 1.0) and the other numbers are the number, n, of lowest values to drop and then the numbers to be averaged after dropping the lowest n values. Example data.txt file would display: 0.5 3 10 70 90 80 20 The program then calculates the weighted average of all those numbers except the lowest n numbers, where…

Assignment First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "MultiTable" (without the quotation marks) that uses nested for loops to print a multiplication table as shown below. The value of each cell should be computed using the values in the row and column headings (e.g., 1 * 1; 1 * 2; 1 * 3; etc.). Make sure to match the below results as shown. * | 1 2 3 4 5 6 7 8 9 ------------------------------- 1 | 1 2 3 4 5 6 7 8 9 2 | 2 4 6 8 10 12 14 16 18 3 | 3 6 9 12 15 18 21 24 27 4 | 4 8 12 16 20 24 28 32 36 5 | 5 10 15 20 25 30 35 40 45 6 | 6 12 18 24 30 36 42 48 54 7 | 7 14 21 28 35 42 49 56 63 8 | 8 16 24 32 40 48 56 64 72 9 | 9 18 27 36 45 54 63 72 81Copy and paste at least one sample run in your source code as a block comment at the bottom below the closing curly brace.
First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "BackwardsStrings" (without the quotation marks) that: Prompts the user at the command line for one 3-character string. After the user inputs that first 3-character string, prompts the user for another 3-character string. Use IF statement to check that both strings are EXACTLY 3 chars long. IF not, THEN print out "Invalid string length for one or both inputs" Use String .charAt(int x) method to manually create a reversed string for each entry Print out the two original input strings with a space between them. Finally print on a separate line the two input strings 'in reverse' (see example below) with a space between them. So, for example, if the first string is 'usr' and the second string is 'bin', your program would output something like the following: The two strings you entered are: usr bin. The two strings in…
First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "PatternMaker" (without the quotation marks) according to the following guidelines. The program prompts the user for five input values: An integer value between 1 and 10 (inclusive) for the number of rows to be printed A second integer value between 1 and 10 (inclusive) for the number of columns to be printed A string value for the starting string of the pattern A string value for the second string of the pattern A string value that separates the first two strings The program must use nested for loops to print a rectangular array of alternating first and second strings of the pattern, separated by the separator string and such that the first string in the first row uses the "first string" provided by the user, but each subsequent row alternates the starting string between the "second string" the user provided and the…

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "WeightedAvgDataAnalyzer" (without the quotation marks), that modifies the DataAnalyzer.java in Horstmann Section 7.5, pp. 350-351 according to the specifications below.The input file should be called 'data.txt' and should be created according to the highlighted instructions below. Note that even though you know the name of the input file, you should not hard-code this name into your program. Instead, prompt the user for the name of the input file.The input file should contain (in order): the weight (a number greater than zero and less than or equal to 1), the number, n, of lowest numbers to drop, and the numbers to be averaged after dropping the lowest n values.You should also prompt the user for the name of the output file, and then print your results to an output file with the name that the user specified.Your…

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "Rooter" (without the quotation marks) to get a positive integer (i.e. any number greater than 0) called "start" from the user at the command line and then find the square root of every number from "start" down through 0. Use a while loop to count down. As an example, if the user entered 8, you would find the square root of 8, then the square root of 7, and so on. Print each square root on a separate line. Include data validation to ensure the user provides a positive integer. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received. Use the Math.sqrt(double a) method to find each square root and output the integer and four decimal positions. You do not need to use the scanner hasNextInt() method. to validate the…
