What will be the result of compiling and executing Test class?
package com.udayan.oca;
public class Test {
public static void main(String[] args) {
String str1 = " ";
boolean b1 = str1.isEmpty();
System.out.println(b1);
str1.trim();
b1 = str1.isEmpty();
System.out.println(b1);
}
}

12. }
13. }
14.
15. class Milk implements Perishable2, Perishable1 {}
16.
17. public class Test {
