/****************** Exercise 3 ******************* From the sections labeled "if-else" and* "return", modify the two test() methods so* that testval is tested to see if it is within* the range between (and including) the* arguments begin and end. (This is a change to* the exercise in the printed version of the* book, which was in error).***********************************************/public class E03_IfElse3 { static boolean test(int testval, int begin, int end) { boolean result = false; if(testval >= begin && testval <= end) result = true; return result; } public static void main(String[] args) { System.out.println(test(10, 5, 15)); System.out.println(test(5, 10, 15)); System.out.println(test(5, 5, 5)); }}

**Since the test( ) methods are now only testing for two conditions, I took the liberty of changing the return value to boolean.
**By using return in the following program, notice that no intermediate result variable is necessary:
