求讲解下这个JAVA程序 最好详细点

private final class MouseCrad implements MouseListener{
private final Cursor cursor1;
private final Cursor cursor2;

public MouseCrad(Cursor cursor1,Cursor cursor2) {
this.cursor1=cursor1;
this.cursor2=cursor2;
}

public void mouseReleased(MouseEvent e) {
setCursor(cursor1);
}
public void mousePressed(MouseEvent e) {
setCursor(cursor2);
}
public void mouseEntered(MouseEvent e) {
setCursor(cursor1);
}
public void mouseExited(MouseEvent e) {
setCursor(cursor1);
}
public void mouseClicked(MouseEvent e) {}}

Answer 1

鼠标动作监听 改变鼠标图标
public void mouseReleased(MouseEvent e) {
setCursor(cursor1);
}//释放鼠标变成cursor1
public void mousePressed(MouseEvent e) {
setCursor(cursor2);
}//按下鼠标时变成cursor2
public void mouseEntered(MouseEvent e) {
setCursor(cursor1);
}//鼠标进入某个区域时变成cursor1
public void mouseExited(MouseEvent e) {
setCursor(cursor1);
}//释放鼠标离开某个区域变成cursor2
public void mouseClicked(MouseEvent e) {}//定义鼠标点击后的动作
}

Answer 2

鼠标事件监听吧
public void mouseReleased(MouseEvent e) {//松开鼠标
setCursor(cursor1);
}
public void mousePressed(MouseEvent e) {//按下鼠标
setCursor(cursor2);
}
public void mouseEntered(MouseEvent e) {//鼠标移入
setCursor(cursor1);
}
public void mouseExited(MouseEvent e) {//鼠标移出
setCursor(cursor1);
}
