Unlocking the Power of Java Methods
When working with Java, understanding how to pass methods as arguments to other methods is crucial. But did you know that you can’t directly pass a method itself as an argument? Instead, you can pass the result of a method call as an argument to another method.
The Role of Method Calls
Take, for instance, the example where the returned value from method2() is assigned as an argument to method1(). This approach allows you to utilize the output of one method as input for another. However, what if you need to pass the actual method as an argument?
Enter Lambda Expressions
This is where lambda expressions come into play. By using lambda expressions, you can pass the method itself as an argument, unlocking a new level of flexibility in your Java programming.
A Real-World Example
Let’s dive into a practical example to illustrate this concept. Consider a Java program with two methods: square() and add(). In this scenario, we’re calling the add() method as an argument of the square() method. As a result, the returned value from add() is seamlessly passed as an argument to square().
Code Breakdown
In this example, we’re witnessing the power of passing methods as arguments firsthand. By leveraging lambda expressions, we can create more dynamic and efficient code that takes our Java programming to the next level.
