i wrote a simple program in java.

Question

class Add{
public static void main(String[] args){
int x = 5, y = 3;
System.out.println("The sum is:" + x + y);
}
}
here the outpur is 53 which is added as string and not integers.
but when i remove "The sum is:" + from the println in 4th line it is added as integers again.
why please tell me

Answer 1

actually , each operand will be added like String ...
case1) 1+2+"a" = 3a

case2.1) "a"+1 = a1 //a1 whole as a String
case 2.2) "a"+1+2 ="a1"+2=a12
//since "a1" is already a String

case3) 1+2 = 3 //no p. in that

Answer 2

correct @TurtleShell
//thats bcz precedence of () operator is greater than + operator
//👉and since , associativity of + operator is from left to right ... so in case 2) there is concatination first & then again concatination rather than addition followed by concatination

Answer 3

To fix what Gaurav is talking about put brackets around the x and y:
System.out.println("The sum is: " + (x + y));
