问题描述
大家好，最后一部分现在是文件阅读。我试过写一个fileReader，但似乎没有改变我的变量rNum的值。
Hi everyone Im on to the last part now which is file reading. i have tried writing a fileReader but seem to not be changing the value of my variable rNum?
任何想法为什么它不会改变在下面的语句？感谢
any ideas on why it wont change in the following statements? thanks
public void readStartFile(String fileName){
int rowNumber=-1;
int colNumber = -1;
int rN= 0;
int cN = 0;
try{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("start.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
String[] temp = strLine.split(" ");
rowNumber = Integer.parseInt(temp[0].substring(1, temp[0].length()));
colNumber = Integer.parseInt(temp[1].substring(1, temp[1].length()));
String colour = temp[2];
if(rowNumber == 0)
rN =0;
else if(rowNumber == 1)
rN =1;
else if(rowNumber == 2)
rN =2;
else if(rowNumber == 3)
rN =3;
else if(rowNumber == 4)
rN =4;
else if(rowNumber == 5)
rN =5;
if(colNumber == 0)
cN =0;
else if(colNumber == 1)
cN =1;
else if(colNumber == 2)
cN =2;
else if(colNumber == 3)
cN =3;
else if(colNumber == 4)
cN =4;
else if(colNumber == 5)
cN =5;
if (colour == "Red")
buttons[rN][cN].setBackground(Color.RED);
System.out.println(""+rN);
System.out.println(""+cN);
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
这是一个来自ButtonColours类的方法。
this is a method from the ButtonColours class. Now how would i set the buttons to the specified colour as what i am doing at the minute does not seem to work.
推荐答案
现在我将按钮设置为指定的颜色，因为我在分钟做的操作似乎不起作用。为了改变你的 JButton 的 Color ，首先你必须记住一件事， buttonObject.setOpaque（true）; 作为非常建议给我一次@Robin :-)。从Java Docs中调用 setOpaque（true / false）
In order to change the Colour of your JButton, first of all you must keep one thing in mind, always to use buttonObject.setOpaque(true); as very much adviced to me once by @Robin :-). As taken from Java Docs the call to setOpaque(true/false)
Sets the background color of this component. The background color
is used only if the component is opaque
这里我修改了代码有点，并添加了一些评论，我添加了什么，看到这是你想要的。
Here I had modified your code a bit, and added some comments as to what I had added, see is this what you wanted.
