How to add two numbers without using any operator in java...

Question

like 5+7=12;//it is ignore.
add(5,7)=12;

Answer 1

Write a method

public static int add(int x, int y){
int z=x+y;
return z;
}

Then you can just call it with your argument of the numbers you want added.

examples:
add(5,7); returns 12
add(5,3); returns 8
add(3,7); returns 10

System.out.println(add(2,6));

Answer 2

Also made another method. it is crude, but it will add(5,7) without using operators, using 2 for loops. check my codes to see it run or here is a rough breakdown of it

static List<String> temp = new ArrayList<String>();

public static int add(int x, int y){
temp.clear();
for(int i=0;i<x;i++){
temp.add("A");
}
for(int i=0;i<y;i++){
temp.add("A");
}
int z = temp.size();
return z;
}

System.out.println(add(5,7));
System.out.println(add(6,4));
