Multiple Markers error

Class SubClass.java line 5 contains a Multiple Markers error. Eclipse asks me to rename file but nothing I write down satisfies it. Could someone help me with this code?

public class SubClass  {
	
	void question()
	{
		super.question();
	}
	
	private int id;
	private String name;
	
	public void SubCLass() {
		System.out.println("ID = " + id + "Name = " + name);
		
	}

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}	
	
}

public class SuperClass extends SubClass  {
	void question(){
		System.out.print("Michael is alive ");
	}
}  

public class TestClass {
	public static void main(String[] args) {
		ToString obj1 = new ToString(1, "Fluffy");
		System.out.println(obj1.toString(obj1));
		
		obj1.question();
	}
}
