执行程序，发现以下错误请版主大虾明示！！！ import java.awt.*; public class Plot extends java.applet.Applet{ Label statLabel = new Label("Current Statistics:"); Graph stats = new Graph();

public void init(){ BorderLayout border = new BorderLayout(); setLayout(border); add("North",statLabel); add("Center",stats); } } class Graph extends java.awt.Canvas{ int[] point = {1,10,3,5,8,7,2,2,5,9,};

public void paint (Graphics screen){ for(int i=0;i<10;i++){ Color blueHue = new Color (0,0,255-(i*20)); screen.SetColor(blueHue); screen.fillRect(0,i*20,point[i]*20,17); } } } Plot.java:19:can not symbol symbol:methhod setColor(java.awt.Color) location:class java.awt.Graphics screen.setColor(blueHue);

import java.awt.*; public class Plot extends java.applet.Applet{ Label statLabel = new Label("Current Statistics:"); Graph stats = new Graph();

public void init(){ BorderLayout border = new BorderLayout(); setLayout(border); add(statLabel,"North"); //add里面先加的是组件，然后才是方向，下面一样 add(stats,"Center"); } } class Graph extends java.awt.Canvas{ int[] point = {1,10,3,5,8,7,2,2,5,9,};

public void paint (Graphics screen){ for(int i=0;i<10;i++){ Color blueHue = new Color (0,0,255-(i*20)); screen.setColor(blueHue); //是setColor不是SetColor，JAVA对大小写太敏感了…… screen.fillRect(0,i*20,point[i]*20,17); } } }
