Which of the following are true about the following code? (Choose all that apply)public class Create {       Create() {            System.out.print("1 ");       }       Create(int num) {            System.out.print("2 ");       }       Create(Integer num) {           System.out.print("3 ");       }       Create(Object num) {          System.out.print("4 ");       }       Create(int... nums) {          System.out.print("5 ");       }       public static void main(String[] args) {            new Create(100);            new Create(1000L);       }}*A. The code prints out 2 4.B. The code prints out 3 4.C. The code prints out 4 2.D. The code prints out 4 4.E. The code prints 3 4 if you remove the constructor Create(int num).F. The code prints 4 4 if you remove the constructor Create(int num).G. The code prints 5 4 if you remove the constructor Create(int num).

Which of the following are output by the following code? (Choose all that apply)public class StringBuilders {        public static StringBuilder work(StringBuilder a, StringBuilder b) {               a = new StringBuilder("a");               b.append("b");               return a;             }            public static void main(String[] args) {                  StringBuilder s1 = new StringBuilder("s1");                  StringBuilder s2 = new StringBuilder("s2");                  StringBuilder s3 = work(s1, s2);                  System.out.println("s1 = " + s1);                  System.out.println("s2 = " + s2);                  System.out.println("s3 = " + s3);                }      }*A. s1 = aB. s1 = s1C. s2 = s2D. s2 = s2bE. s3 = aF. s3 = nullG. The code does not compile.
