Question

PrintWriter out = 
 new PrintWriter("C:UsersSlerigDesktopgnuplotinarycannonballOutput.txt");

This is my sample code. It is quite simple. It throws a "Invalid Escape Character" error because of the backslashes. How do I get around this? Programming in Java btw.

Answer 1

You ll have to escape with \ in your string (or use / instead) Use

PrintWriter out = 
 new PrintWriter("C:\Users\Slerig\Desktop\gnuplot\binary\cannonballOutput.txt");

Answer 2

如果你不想用<代码>//>/代码>铺设你的道路, Java将自动转换。

public class Test
{
    public static void main(final String[] args)
    {
        final File f = new File("C:/tmp");
        for (String s : f.list())
        {
            System.out.println("filename = " + s);
        }
    }
}

Answer 3

绕过<条码>,你仅需要使用<条码>/。

new PrintWriter("C:\Users\Slerig\Desktop\gnuplot\binary\cannonballOutput.txt");
