Question

What display is produced by the execution of this JAVA program if we make the following call
f(0,0).
Please explain your answer

public class function {

   static void f(int x){
       System.out.println(1);
   }

   static void f(double x){
       System.out.println(2);
   }

   static void f(char x){
       System.out.println(3);
   }

   static void f(long x){
       System.out.println(4);
   }

   public static void main(String[] args) {

  
   }
}

ANSWER : HERE IS THE ANSWER FOR YOUR QUESTION:

----------------------------------------------------------------------------------------------------------------

CODE:

public class function {

static void f(int x){
System.out.println(1);
}

static void f(double x){
System.out.println(2);
}

static void f(char x){
System.out.println(3);
}

static void f(long x){
System.out.println(4);
}

public static void main(String[] args) {
f(0,0);
  
}
}

----------------------------------------------------------------------------------------------------------------

SNIPPET:

1- public class function { static void f(int x){ System.out.println(1); static void f(double x){ System.out.println(2); static void f(char x){ System.out.println(3); 15 - static void f(long x){ System.out.println(4); public static void main(String[] args) { f(0,0);

----------------------------------------------------------------------------------------------------------------

OUTPUT:

input Compilation failed due to following error(s). Main.java:20: error: no suitable method found for f(int, int) f(0,0); method Main.f(int) is not applicable (actual and formal argument lists differ in length), method Main.f(double) is not applicable (actual and formal argument lists differ in length) method Main.f(char) is not applicable (actual and formal argument lists differ in length), method Main.f(long) is not applicable (actual and formal argument lists differ in length) 1 error

The output is due to function paramter mismatch during the function call. we are passing 2 paramters value as 0, 0 during function call but all the function defined has only one argument. thus , actaul and formal argument differ in length and compiler is not able to find the correct version of method which is having 2 paramters as input.

thus ,we get the error as shown .
