Question

求帮我解答关于java连连看代码的一点问题

JLabel fractionLable=new JLabel("0"); //分数标签
public void fraction(){
fractionLable.setText(String.valueOf(Integer.parseInt(fractionLable.getText())+100));
}
fractionLable.setText(String.valueOf(Integer.parseInt(fractionLable.getText())));
northPanel.add(fractionLable);
这几句是什么意思 求详细解释

Answer 1

JLabel fractionLable=new JLabel("0");//创建标签,value=0
fractionLable.setText();//给标签赋值
String.valueOf(Integer.parseInt(fractionLable.getText())+100)//将标签获得值+100然后取整，最后将它变成字符串形式
fractionLable.setText(String.valueOf(Integer.parseInt(fractionLable.getText())));//获得标签新值
northPanel.add(fractionLable);//将标签添加到容器中
