Split method for string objects in Java

　　

There is a String.Split () method in the Java.lang package, which returns a string[] array, and today encountered a problem that he did not notice:

1. Special separators

String str1 = "123|456|789"; System.out.println (Str1.split ("|") [0]);

The result is 1.

The note here is "|" As a delimiter to write like this

System.out.println (Str1.split ("\\|") [0]);

Similarly, if you use "." The delimiter is also called plus 2 backslashes,

2. Multiple separators

String str1 = "123 aa 456 bb 789"; System.out.println (Str1.split ("AA|BB") [0]); System.out.println (Str1.split ("AA|BB") [1]); System.out.println (Str1.split ("AA|BB") [2]);

The result is 123.

456

789

Multiple separators can be used with the ' | ' Link up
