}A developer writes the following code:
int a = 5; int b = 2;
double result = a / b; System.out.println(result);
What is the output?

String s1 = "Java";
String s2 = new String("Java");
String s3 = "Java";
System.out.println(s1 == s2);
System.out.println(s1.equals(s2));
System.out.println(s1 == s3);
