classes and objects in java code example
Example 1: java create new object
Car mycar = new Car();
Example 2: How to make a class in Java?
public class Object {
public int a = 1;
private int b = 5;
int c = 0;
void setB(int B)
{
b = B;
}
int getA()
{
return b;
}
}
Example 3: java class
public class Lightsaber {
private boolean isOn;
private Color color;
public Lightsaber(Color color) {
this.isOn = false;
this.color = color;
}
public Color getColor() {
return color;
}
public boolean getOnStatus() {
return isOn;
}
public void turnOn() {
isOn = true;
}
public void turnOff() {
isOn = false;
}
}
public class test {
public static void main(String[] args) {
Lightsaber yoda = new Lightsaber(green);
yoda.turnOn();
}
}
Example 4: how to make a class in java
public class Main {
public static void main (String[] args) {
System.out.println("Hello World");
}
}
Example 5: classes in java
public class MathTest {
public static void main(String[] args) {
class MathAdd {
int num1;
int num2;
public int addNumbers() {
int addThemUp = num1 + num2;
return addThemUp;
}
}
MathAdd addition = new MathAdd();
addition.num1 = 10;
addition.num2 = 20;
System.out.println(addition.addNumbers());
}
}
Example 6: using class in java
public class HelloWorld {
public static void main(String[] args) {
class User{
int score;
}
User dave = new User();
dave.score = 20;
System.out.println(dave.score);
}
}
