Java Singleton Pattern

I’ve noticed that there is no Java Singleton sample in my blog. Here it is:

MySingleton.java

public class MySingleton
{
 
  private final static MySingleton instance = new MySingleton();
  private String test = null;
 
  private MySingleton()
  {
    super();
  }
 
  public static MySingleton getInstance()
  {
    return instance;
  }
 
  public String getTest()
  {
    return test;
  }
 
  public void setTest(String test)
  {
    this.test = test;
  }
}

Execution:

  MySingleton singleton = MySingleton.getInstance();
  singleton.setTest("This is a test.");
