following two methods are supposed to compute the absolute value of 1 number and the absolute value of the sum of 2 numbers respectively. Find and fix 2 errors to make these methods work properly. public static int abs(int n) { ............................ return n <= 0 ? n : -1 * n; ............................ } public static int abs(int a, int b) {............................ int c = a + b; ............................ return abs(a,b); ........................

Besides main() this program has one method that computes the amount of raise and the new salary for an employee.  The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary {    public static void main (String[] args)    {        Declare variables       Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the  salary without change; otherwise, compute and print new salary and raise amount main() must display the message    } }   Note:- Please type and execute this java program and also need an output for this java program as soon as possible.

public static int test(int n, int k) { if (k == 0 || k == n) { return 1; } else if (k>n) { return 0; } else { return test(n-1, k-1) + test(n-1, k); } ww For each of the following calls, indicate the output that is produ test(7,5); test(6,4); test(4,5); test(8,3); test(5,5);

Program to compute interest = p * r * t, where p = $10K, rate = 6%, t = 10 years; these values are to be passed from main()   Besides main() the program has two methods: one that computes the   interest and on that rounds interest to two decimal places public class DisplayInterest     public static void main(String[] args)     call a method that will do the computation with values for the above     variables; with the exception of year, they are double     main() displays computed interest  after rounding                      computation method()     rounding method()           Note:- Please type and execute this java program and also need an output for this java program.
