In this article, we will understand how to pass method call as arguments to another method. We can call a method from another class by just creating an object of that class inside another class. After creating an object, call methods using the object reference variable.
Below is a demonstration of the same −
Input
Suppose our input is −
Enter two numbers : 2 and 3
Output
The desired output would be −
The cube of the sum of two numbers is: 125
Algorithm
Step 1 - START Step 2 - Declare two variables values namely my_input_1 and my_input_2 Step 3 - We define a function that takes two numbers, and returns their sum. Step 4 - We define another function that takes one argument and multiplies it thrice, and returns the output. Step 5 - In the main function, we create a new object of the class, and create a Scanner object. Step 6 - Now, we can either pre-define the number or prompt the user to enter it. Step 7 - Once we have the inputs in place, we invoke the function that returns the cube of the input. Step 8 - This result is displayed on the console.
Example 1
Here, the input is being entered by the user based on a prompt. You can try this example live in ourcoding ground tool .
import java.util.Scanner; public class Main { public int my_sum(int a, int b) { int sum = a + b; return sum; } public void my_cube(int my_input) { int my_result = my_input * my_input * my_input; System.out.println(my_result); } public static void main(String[] args) { Main obj = new Main(); int my_input_1, my_input_2; System.out.println("Required packages have been imported"); Scanner my_scanner = new Scanner(System.in); System.out.println("A reader object has been defined "); System.out.print("Enter the first number : "); my_input_1 = my_scanner.nextInt(); System.out.print("Enter the second number : "); my_input_2 = my_scanner.nextInt(); System.out.println("The cube of the sum of two numbers is: "); obj.my_cube(obj.my_sum(my_input_1, my_input_2)); } }
Output
Required packages have been imported A reader object has been defined Enter the first number : 2 Enter the second number : 3 The cube of the sum of two numbers is: 125
Example 2
Here, the integer has been previously defined, and its value is accessed and displayed on the console.
public class Main { public int my_sum(int a, int b) { int sum = a + b; return sum; } public void my_cube(int my_input) { int my_result = my_input * my_input * my_input; System.out.println(my_result); } public static void main(String[] args) { Main obj = new Main(); int my_input_1, my_input_2; my_input_1 = 3; my_input_2 = 2; System.out.println("The two number is defined as " +my_input_1 +" and " +my_input_2); System.out.println("The cube of the sum of two numbers is: "); obj.my_cube(obj.my_sum(my_input_1, my_input_2)); } }
Output
The two number is defined as 3 and 2 The cube of the sum of two numbers is: 125
