I can provide you with simple Java code examples along with detailed explanations and outputs. Here are 6 examples that you can try:
Example 1: Hello World Program
java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
Explanation:
– The code defines a class named `HelloWorld`.
– Inside the class, there is a `main` method which is the entry point of the program.
– The `main` method prints out "Hello, World!" to the console using `System.out.println`.
Output:
Hello, World!
Example 2: Calculation of Circle Area
java
import java.util.Scanner;
public class CircleArea {
public static void main(String[] args) {
final double PI = 3.14159;
Scanner input = new Scanner(System.in);
System.out.print("Enter the radius of the circle: ");
double radius = input.nextDouble();
double area = PI * radius * radius;
System.out.println("The area of the circle is: " + area);
}
}
Explanation:
– This code calculates the area of a circle based on the input radius provided by the user.
– The program uses the formula: area = π * radius^2.
Output:
Enter the radius of the circle: 5
The area of the circle is: 78.53975
