Java truncation string

There are two methods to intercept a string: The sustring () method and the split () method.

 

 

Small Example Program

Substring:

Truncation date,

System. Out. println (new date (). tostring (). substring (0, 20 ));

The result is the first 20 characters;

Split;

 

String S = "this is a string with space ";

 

String B [] = S. Split ("//");

For (INT I = 0; I <B. length; I ++ ){

System. Out. println (B [I]);

}

 

The result is

This

Is

A

String

With

Space

An error may occur if '//' is removed from the method by printing it out every space.
