Question

Predict the output for the following:

char c1=’a’, c2=’A’

int c=a+b;

System.out.println((char)(a-50));​

Answer 1

We will get an error when we run the given program.

Explanation:

Program:

public class Main

{

public static void main(String[] args)

{

char c1='a', c2='A';

       int c=a+b;

       System.out.println((char)(a-50));

}

}

Output:

Main.java:6: error: cannot find symbol

   int c=a+b;

         ^

 symbol:   variable a

 location: class Main

Main.java:6: error: cannot find symbol

   int c=a+b;

           ^

 symbol:   variable b

 location: class Main

Main.java:7: error: cannot find symbol

   System.out.println((char)(a-50));

                             ^

 symbol:   variable a

 location: class Main

3 errors

We get an error because, we did not declared a and b variables.
