JAVA围棋棋盘等基础题
第一个：用Integer类的parseInt方法：
如:int a=parseInt("1111111","2");那么a就是127了。(好像是parseInt("2","1111111");自己试试)
第二个：
static final int huLu=7.5;//中元美元汇率
int a=100*huLu
System.out.println("￥"+Integer.toString(a));
第三个：做一个围棋棋盘的图片，加入程序就是了。
java编程问题
我自己写了一个简单的程序，可选择落子的先后顺序，重新开始，最后判断某一方是否为五子连珠。选择落子的先后顺序，只需定义一个boolean变量，每次切换取其反值；重制棋盘或重新开始就把棋盘重新绘制一遍；判断某一方是否为五子连珠，就判断某方的每个棋子，以它为中心与之紧邻的水平，垂直，左斜，右斜四个方向是否有五子连珠。用一个二维数组position存储棋盘上的棋子情况，position[x][y]=1,0,-1分别表示棋盘的第x行第y列下有黑子，无子，白子。源代码如下：

不是很完善，希望对你有帮助。
java 实现围棋盘每个格子装一颗粮食，以后每个格子增加一倍到最后总共有多少粮食。
第一个格子是2的0次方，第二个是2的1次方，第3个是2的2次方，。。。
格子数cellNumber就会有2^0+2^1+2^2+...+2^(cellNumber-1)个。楼上的那个不行，int在内存中占32位，棋盘数有324个，所以会溢出。
int cellNumber=324;
BitSet bits = new BitSet();
bits.set(0, cellNumber);
System.out.println(new BigInteger(1,bits.toByteArray()).toString());
java canvas画围棋棋盘
/*首先，
应用程序必须为 Canvas 类创建子类，以获得有用的功能（如创建自定义组件）。必须重写 paint 方法，以便在 canvas 上执行自定义图形。
以下是代码
*/
import java.awt.Canvas;
import java.awt.Font;
import javax.swing.*;
public class P {
public static void main(String[] args){
JFrame jf=new JFrame();
jf.setVisible(true);
jf.setLocation(200,200);
jf.setSize(300, 300);
jf.add(new a());
}
}
class a extends Canvas{
public void paint(java.awt.Graphics g){
int j=0,i=0;
while(i6){//for循环也可以
g.drawLine(0, 20*i, 100, 20*i);//横线,y坐标不变
g.drawLine(20*i, 0, 20*i, 100);
i++;
}
g.drawString("楚河汉界", 20, 130);
i=0;
while(i6){
g.drawLine(0,160+20*i, 100, 160+20*i);
g.drawLine(20*i, 160, 20*i, 260);
i++;}
}
}
虽然画出来了，但我想简化两个循环，如下：
class a extends Canvas{
public void paint(java.awt.Graphics g){
int j=0,i=0;
do{//用for循环也可以
if(j==0){
g.drawLine(0, 20*i, 100, 20*i);//横线
g.drawLine(20*i, 0, 20*i, 100);
}
else{
g.drawLine(0,160+20*i, 100, 160+20*i);
g.drawLine(20*i, 160, 20*i, 260);
}
if(i==5j==0){j=1;i=-1;g.drawString("楚河汉界", 20, 130);}//因为判断第一次之后，i会被加一次，而这次是没有画线的，会导致少了一条线，所以i=-1
i++;
}while(i6);
}
}
