Methods Output
What will be the output of the following program.
`class MethodsTest{    public static void main(String s[])    {        int a = 34;        int b = 56;        int c = sum(a, b);        System.out.println("c = " + c);    }        public static int sum(int a, int b)    {        System.out.println("a = " + a + " b = " + b);        return a + b;    }}`

 A. a = 34 b = 56c = 90 B. a = 56 b = 34c = 90 C. c = 90 D. Compilation Error

here we are creating 3 integer variable i.e..

int a=34;
int b=56;
int c=sum(a,b);

public static void main(String s[])  //main method

public static int sum(int a,int b)     //sum method accepts two arguments and return integer type value

here two methods are used in the programe both are static and here in the method we are calling sum(a,b) method but using static keyword .i.e..one static method can call another static method only ..

in the third statement the control goes to the sum(a,b) method by passing two arguments at the calling part in this method the a and b values are printed
i.e...   //                   a=34 b=56

and in the return statement the addition of both values are sent to the calling part i.e..90 and asssigned to variable c
and c value is printed..c=90

Ans is A

In above program the concept of function is used.

--Here,two integer variables are declared with name a and b.
a=34
b=56

After that function sum () is called by passing these parameters I.e. a and b.

---In method sum() value of a and b are printed.
a=34
b=56
After that a+b I.e. 90 is returned to variable c.

---In main method(), c holds the value 90 and it is printed.

a=34 b=56
c=90
