Question

1. Predict the return data type of the following: int a; double b; c = a*b; System.out.println(c); ​

Answer 1

ERROR WHILE COMPILING

ERRORS :

CANNOT CONVERT FROM INT TO DOUBLE ,

' int ' / ' double ' should be inputed before variable c ,

There are no values used for variables a , b .

Correction :

import java.util.*;

public class Q

{

public static void main(String args[])

{

// You Can Change The Data Type To Double .

int a = 4 ;

int b = 2 ;

int c = a * b ;

System.out.println(c);

}

}

Output = 8
