使用Maven Ant更改文件路径

Question

我是新来的。我有这样一个简单的项目:

public class test {
    public test() {
        // TODO Auto-generated constructor stub
    }
    public static void main(String[] args) {
        String path = "test\template.txt"
        FileOutputStream fileOut = new FileOutputStream(path);
    }
}

我想改变我的字符串"路径"形式的蚂蚁任务。我可以这样做吗?

建议

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class Application {
    public Application() {
        // TODO Auto-generated constructor stub
    }
    public static void main(String[] args) throws FileNotFoundException {
        if (args.length < 1) {
            System.out.println("Usage " + Application.class.getSimpleName() + " template-file");
        }
        String pathStr = args[0];
        File path = new File(pathStr);
        if (path.exists()) {
            System.err.println("Already a file exists at location '" + path + "'");
        }
        FileOutputStream fileOut = new FileOutputStream(path);
    }
}
