How to convert int to String in java

Question

public class Apples {
    public static void main(String args[]){
        String base;
        int no1 = 72;
        int no2 = 75;

        base = (String)(no1 + no2);
        System.out.println(base);
    }
}

The Above code generates error and says that it cannot convert int to String. Why is this so ?

I am a beginner and from my knowledge I guess that type-casting should work here.

You cannot do a _cast_ here simply because an `int` is not a `String`. They are different types and do not have a type relationship. So you have to _convert_: `String.valueOf(no1) + String.valueOf(no2)`. — Seelenvirtuose, Feb 21 '16 at 08:22

You can use valueOf() like this:

String base = String.valueOf(no1 + no2);

Alternatively, If you just want to print the number then you can directly do:

System.out.prinltn("Number: " + (no1 + no2));

This works but gives the sum of the two instead of 72 + 75 = 7275. Its Silly but I need it – dumbPotato21 Feb 21 '16 at 07:54
That is because you might not be enclosing `no1 + no2` in `()`. You have to do: `(no1 + no2)` and not just `no1 + no2`. – user2004685 Feb 21 '16 at 07:58
you can do `System.out.println("number:"+n1+"+"+n2);` – roony Feb 21 '16 at 08:03
@roony That will give `7275` and not `147` – user2004685 Feb 21 '16 at 08:05
it gives 72+75, which is what he said he wants @user2004685 – roony Feb 21 '16 at 09:46
He want the addition of two numbers i.e. `72` and `75` but getting concatenation i.e. `7275` instead. That is what I understood. Correct me if I'm wrong. – user2004685 Feb 21 '16 at 09:48
