String.split() 测试

1、去掉所有 \r \n :

 1     public static void main(String[] args)
 2     {
 3         String str = "A\r\nB\nc";
 4         String[] strs = str.split("[\r\n]+");
 5         for (int i=0; i<strs.length; i++)
 6             System.out.println(strs[i]);
 7         
 8         System.out.println("");
 9         
10         str = "Ac\r\r\nB1\n\nc2";
11         strs = str.split("[\r\n]+");
12         for (int i=0; i<strs.length; i++)
13             System.out.println(strs[i]);
14     }

输出为:

1 A
2 B
3 c
4 
5 Ac
6 B1
7 c2

 

2、

代码:

 1     public static void main(String[] args)
 2     {
 3         String str = "a c v  f   b       t  ";
 4         String[] strs = str.trim().split(" +", 3);
 5         System.out.println("strs.length(1) : "+strs.length);
 6         for (int i=0; i<strs.length; i++)
 7             System.out.println(strs[i]);
 8         
 9         System.out.println("");
10         str = "a cccccc";
11         strs = str.trim().split(" +", 3);
12         System.out.println("strs.length(2) : "+strs.length);
13         for (int i=0; i<strs.length; i++)
14             System.out.println(strs[i]);
15     }

输出:

strs.length(1) : 3
a
c
v  f   b       t

strs.length(2) : 2
a
cccccc

 

 

 

C
