java怎么在panel面板里添加文字

方法1、复写paint方法

public void paint(Graphics g){

g.drawString("你写的话")

}

方法2创建一个JLable 用add方法添加进去

从工作台中输入用java.util.Scanner。Scanner s = new Scanner(System.in)String str=s.next()

如果你需要的是那种桌面应用程序的话，就写一个文本框空间，Text text=new Text()String str=text.getText()；

import java.awt.Color

import java.awt.Frame

import java.awt.Graphics

public class DrawString extends Frame{

private static final int spacing = 20 //文字与图片边界的空白

private static final int wordNum = 7 //文字字号

private Color strColor

private StringBuffer message

private int pictureWidth

private int pictureHight

public void paint(Graphics g){

Color c = g.getColor()

g.setColor(strColor)

StringBuffer msg = message

int strNumPerLine = (pictureWidth - spacing) / wordNum

int strLineNum = message.length() / strNumPerLine

for(int l=strLineNum,n=0 l<0l--){

msg.substring(n, strNumPerLine)

g.drawString(msg.toString(), wordNum, wordNum * strNumPerLine)

n = strNumPerLine

}

g.setColor(c)

//this.draw(g)

}

public DrawString(Color strColor, StringBuffer message, int pictureWidth, int pictureHight) {

this.strColor = strColor

this.message = message

this.pictureWidth = pictureWidth

this.pictureHight = pictureHight

}

}
