4. What will be the output of following Java program?
class Test{ public static void main (String[] args) { int arr1[] = {1, 2, 3}; int arr2[] = {1, 2, 3}; if (arr1.equals(arr2)) System.out.println("Same"); else System.out.println("Not same"); }}
What will happen when you compile and run the following code? #1. public class Test{
public static void main(String[] args){
int a = 10, b = 0;
while( a + 2 < 10 || b - 2 > 0){
System.out.println(a);
}
}
}
#2. public class Test{
public static void main(String[] args){
int a = 0, b = 10;
while(b - 40 > 0){
b -= 2;
while(a + 12 < 10){
a += 2;
if(a == b)
continue;
System.out.print(a + " " + b + ", ");
}
