object with different classnames in java code example

Example 1: java class

public class Lightsaber {
  // properties
  private boolean isOn;
  private Color color;
  
  // constructor
  public Lightsaber(Color color) {
    this.isOn = false;
    this.color = color;
  }
  
  // getters
  public Color getColor() {
    return color;
  }
  public boolean getOnStatus() {
    return isOn;
  }
  
  // setters
  public void turnOn() {
    isOn = true;
  }
  public void turnOff() {
    isOn = false;
  }
}



// Implementation in main method:
public class test {
  public static void main(String[] args) {
    Lightsaber yoda = new Lightsaber(green);
    yoda.turnOn();
  }
}

Example 2: using class in java

public class HelloWorld {
  public static void main(String[] args) {
    
    // how to use class in java
    class User{
    	
    	int score;
    	
    	// method that can be used outside the class
    	public boolean hasWon(){
    		if(score >= 100){
    			return true;
    		} else {
    			return false;
    		}
    	}
    }
    
    User dave = new User();
    
    dave.score = 20;
    
    System.out.println(dave.hasWon());
    
 
  }
}
