之前的两篇文章：java实现两人五子棋游戏(二) 画出棋盘；java实现两人五子棋游戏(三) 画出棋子；java实现两人五子棋游戏(四) 落子动作的实现；Java实现两人五子棋游戏(五) 判断是否有一方胜出，可以点击查看。
前面我们已经画好棋盘和棋子，并可以*落子，且可以判断棋盘中是否有五连珠。接下来的工作是，每次落子后交换行棋方（即将下一棋子颜色由白->黑或黑->白），并将胜出判断增加颜色判断条件（棋盘上存在五连珠->棋盘上存在同色的五连珠）。
主模块main.java和棋子类chessman.java不变，我们要对drawchessboard.java中的落子函数mousepressed和五连珠判断函数iswin做一下调整。

public class chessman {
private int color;//1-white，0-black
private boolean placed = false;
int matchcount = 1;
public chessman(int color,boolean placed){
this.color=color;
this.placed=placed;
}
public boolean getplaced() {
return placed;
}
public void setplaced(boolean placed) {
this.placed = placed;
}
public int getcolor() {
return color;
}
public void setcolor(int color) {
this.color = color;
}
}

第一步，修改mousepressed函数，使得每次落子后，都将行棋方让给对家（即每次落子都改变棋子颜色）
drawchessboard.java中的mousepressed函数部分，只要每次都修改chesscolor的值即可。

运行一下
第二步，将胜出判断增加颜色判断条件（棋盘上存在五连珠->棋盘上存在同色的五连珠）
在iswin函数的判断条件上，加上对chessman.getcolor的颜色判断
iswin函数代码
