How to determine whether a string is a file path in java

我们可以使用matches()方法与正则表达式进行判断。

matches() 方法用于检测字符串是否匹配给定的正则表达式。

具体的正则表达式为：【^[A-z]:\\\$.+?\\\$*$】。

（视频教程推荐：java视频）

具体代码：

	public static void main(String[] args) {
//		String source = "z:\\java\\kl\\$kls\\";
		String source = args[0]+File.separator;
		String targer = args[1]+File.separator;
		System.out.println(source);
		System.out.println(targer);
		if(source.matches("^[A-z]:\\\\(.+?\\\\)*$") && targer.matches("^[A-z]:\\\\(.+?\\\\)*$")){
			System.out.println("磁盘路径正确。。。");
		}
		
	}
