今天在做项目的时候发现一个奇怪的问题
File file = new File("d:\\a.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String text = "";
while ((text = br.readLine()) != null) {
String[] s = text.split("|");
for (int i = 0; i < s.length; i++) {
System.out.print("切割字符串" + s[i] + "\t");
}
System.out.println();
}
br.close();
运行的结果
发现每一个字符都给我切割了，后来在网上查到，当以 | 切割的时候一定要注意使用转义字符
File file = new File("d:\\a.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String text = "";
while ((text = br.readLine()) != null) {
String[] s = text.split("\\|");
for (int i = 0; i < s.length; i++) {
System.out.print("切割字符串" + s[i] + "\t");
}
System.out.println();
}
br.close();
搞定收工~
