Java programs pass methods as parameters to other methods

　 　 Java Examples Comprehensive

In this example, we will learn how to pass methods as parameters to other methods in Java

To understand this example, you should know the followingJava ProgrammingTopic：

Example1：The Java program passes methods as parameters to other methods

class Main {
　　//Calculate the total sum
　　public int add(int a, int b) {
　　　　//Calculate the total sum
　　　　int sum = a　+　b;
　　　　return sum;
　　}
　　//Calculate Square
　　public void square(int num) {
　　　　int result = num　*　num;
　　　　System.out.println(result);　　　　//　prints　576
　　}
　　public static void main(String[] args) {
　　　　Main obj = new Main();
　　　　//　Calling the square() method
　　　　//　Passing add() as a parameter
　　　　obj.square(obj.add(15,　9));
　　}
}

In the above example, we created two methods named square() and add(). Note this line,

obj.square(obj.add(15,　9));

Here, we are calling the square() method. The square() method takes the add() method as its parameter.

With the introduction of lambda expressions, it has become easier to pass methods as parameters in Java. For more information, please visitJava Lambda Expressions as Method Parameters.
