Given the code fragment:
System.out.println(2 + 4 * 9 - 3); //Line 21
System.out.println((2 + 4) * 9 - 3); // Line 22
System.out.println(2 + (4 * 9) - 3); // Line 23
System.out.println(2 + 4 * (9 - 3)); // Line 24
System.out.println((2 + 4 * 9) - 3); // Line 25
Which line of codes prints the highest number?
System.out.println(2 + 4 * 9 - 3); //Line 21
System.out.println((2 + 4) * 9 - 3); // Line 22
System.out.println(2 + (4 * 9) - 3); // Line 23

Given:
public class Test1 {
static void doubling (Integer ref, int pv) {
ref =20;
pv = 20;
}
public static void main(String[] args) {
Integer iObj = new Integer(10);
int iVar = 10;
doubling(iObj++, iVar++);
System.out.println(iObj+ ", "+iVar);
