[DUPLICATE] What return value does in java.please somebody explain

Answer 1

depends on the purpose of method , suppose U just wanted to print "hello world" using a method , then return type will be void [as U are printing a value , not returning something]
example 1) :::
static void printHelloWorld(){
System.out.println("hello world");
}

example 2)
now if U want to get sum of 2 numbers(let are integers ) using method getSum , here return type will be of integer as sum of 2 integers will obviously an integer only

int sum = getSum (1,2);
//method call from the main method

//method definition
static int sum (int a , int b){
return a+b;
}

Answer 5

but what if I don't type return in there but just write SOP (a+b)

it is gonna ask me the values of a and b while the code runs.
if yes what is the return good for
and please correct me wherever I am wrong

Answer 6

OK OK wait if I say that return function changes a method into a variable containing the value of the method after execution of the method so that it can be used anywhere
will it be correct
