Thread: eclipse help

but if we assume the rest of the code as following:

public class Main {
 
	public static void main(String args[]){
 
		Course x=new Course();
 
		Activity y=new Activity();
		String [B]input[/B]=args[0];
		x.register(input);
		y.registerA(input);
	}
 
}
 
public class Course {
Names n=new Names();
public void register(String k){
	n.check(k);	
}
}
 
public class Activity extends Course{
 
	public void registerA(String e){
 
		n.checkA(e);
	}
 
}
 
public class Names {
	int i;
 
	String[] [B]list[/B]={"mos","mona","ali"};
	Result m=new Result();
	void check(String s){
 
		for(i=0;i<=2;i++){
			if (list[i]==s) {m.success();
			break;
			}
			else if (i==2) {
				m.fail();}
			else {
				continue;
			}
 
		}
 
	}
 
	void checkA(String b){
 
		for(i=0;i<=2;i++){
			if (list[i]==b) {m.successA();
			break;
			}
			else if (i==2) {m.failA();}
			else {
				continue;
			}
 
		}
 
	}
 
	}
 
public class Result {
	public void success(){
		System.out.println("reg in course");}
	public void fail(){
		System.out.println("u r not registered");
	}
	public void failA(){
		System.out.println("u r not registered in act");
	}
	public void successA(){
		System.out.println("in the act");
	}
 
}

why the compiler assumed that the reference to the element value in the list array is equals to the reference of the "input" object when the value actually referenced by the array?? you have an illustration to this??
