Functions in Java
In this post, you will learn how to work with functions so that you can use that same knowledge and thus evolve.
- a function is an organized and reusable piece of code that is used to perform a single related action;
- functions provide better modularity and a high degree of code reuse;
- it is not possible to create a role inside another role.
package com.caffeinealgorithm.programminginjava;
public class Functions {
public void Run() {
personalData();
personalData();
personalData();
}
public void personalData() {
System.out.println("Name: Nelson Silva");
System.out.println("Age: 25");
System.out.println("Nationality: Portuguese");
}
}
