little help with assigning values to arrays!!

[prasanth miriyala]

Ok this seems a bit wierd but I couldnt able to figure out whats wrong with my code:

Problem: I want to assign values to array from another variable but its comes up with an error.

please help me with this

import java.awt.Graphics;
import java.awt.Color;
import java.awt.Event;
import java.util.*;


public class MouseEvent extends java.applet.Applet  {
	int x[] = new int[10];
	int y[] = new int[10];
	int points = 0;
	String s;
	
	
	public boolean mouseDown(Event evt, int x, int y){
	
	        x[points]= x;
		y[points] = y;
		points++;
		

		// s = "mouse down at:" + x + "," + y ;
		return true;
		
	}
	
	public boolean mouseUp(Event evt, int x, int y){
		
		x[points]= x;
		y[points]= y;
		points++;
	
		s = "mouse up at:" + x +"," + y;
		repaint();
		return true;
		
	}
	
	public void paint(Graphics g){
	
		g.drawString(s,5,20);

		g.drawPolygon( x,  y, points);
		
		
		
	}
}

"[...] its comes up with an error" is not actually a helpful diagnostic. Telling us *what* the error is makes it much, *much* easier to help.

See the TellTheDetails and ItDoesntWorkIsUseless FAQ entries.

Telling us *specifically* you're trying to do is also helpful--it's hard for us to guess your intent. I will say, however, that any code that writes to an array of bounded length without checking the index before writing is likely to break.

my apologies my problem is when I'm trying to assign the value to an array (x[points] = x;) at line 16 and line 17 its giving me an error in ecllipse;

error: The type of the expression must be an array type but it resolved to int.

Prasanth:

I see what the error is. Look at the variables in your mouseDown() and mouseUp() methods, and compare them to your array variables. That's where the problem lies.

 public boolean mouseDown(Event evt, int x, int y){  
       
            x[points]= x;  //or use this.x[points]= x;
        y[points] = y;  //or use this.y[points]= y;
         points++;  
           
  
        // s = "mouse down at:" + x + "," + y ;  
         return true;  
           
    }  

yes. As mentioned eariler ,Here x[points] x is your argument x . it is not your array x which is the instance variable
