PROBLEM STATEMENT: Return the longest String! public class LongestString{public static String solution(String firstWord, String secondWord){// ↓↓↓↓ your code goes here ↓↓↓↓return null;}} Can you help me with this Java Question

True or False: (a) In a debugger, we can choose whether to step into, step over, or step out of a particular method call. (b) Debuggers, tests, and println() statements are all legitimate ways to help us find errors in our code.

public class Test { } public static void main(String[] args){ int a = 10; System.out.println(a*a--); }

public class Test { } public static void main(String[] args) { String str = "Salom"; System.out.println(str.indexOf('t)); }

Java true or false: The method public boolean simpleMethod() { return true; } is a valid mutator?
