What will be the output of the following statements?

int a = 3;
System.out.println(" " + (1 + a)); 
System.out.println(" " + 1 + a);

Find the output of the following code.

String str = "I Love My Family";
System.out.println(Integer.toString(str.length()));
System.out.println(str.substring(12));

Write the value of n and m after execution of the following code.

int m;
int n;
m = 5;
n = (5 * ++m) % 3;
System.out.println("n = " + n + "m =" + m);

Predict the output

(a) Math.pow(3.4, 2) + 2 * Math.sqrt(64)

(b) Math.ceil(3.4) + 2 * Math.floor(3.4) + 2
