Answer 1

Kaung Myo Htet add a return at or near the bottom like this

// approximately line 26 <-
return ;
}
}
} // still line 29 <-

After I did this in your code the error stopped and worked correctly telling me the answer was either too low or too high

Answer 2

/*
By putting return ; you can not run loop repeatedly, you can enter value single time only.. so there is no need to use loop then. Like this :
*/

import java.util.Scanner;

public class Program {
// Can u guess a number
public static void main(String[] args) {

int a = 0, answer = 7;
Scanner sc = new Scanner(System.in);
a=sc.nextInt();
System.out.println("Enter Number"+ a);

if (a==answer)
System.out.println("You are Right");

else{
System.out.println("You are Wrong");
if(a<answer)
System.out.println("Too Low");

else
System.out.println("Too High");
}

}
}

Answer 3

Put your code in a script on sololearn playground and link it. DO NOT paste the code into the description.

Answer 4

Save code as java file then from 3 dots graph like same as top left corner symbol in this thread, select share option or copy to clip board then paste link here.
Your code have no error but it asks input values until a!=answer is false so until you enter 7 , the loop runs. If you don't enter any value then you see error "Exception in thread.... "

If you entering single value then don't use while loop..
Hope it helps...
