java split用法详解及实例代码
作者:LowProgrammer
这篇文章主要介绍了java split用法的相关资料,并附实例代码,帮助大家学习参考,需要的朋友可以参考下
public String[] split(String regex) 默认limit为0
public String[] split(String regex, int limit)
当limit>0时,则应用n-1次
public static void main(String[] args) { String s = "boo:and:foo"; String[] str = s.split(":",2); System.out.print(str[0] + "," + str[1]); }
结果:
boo,and:foo
当limit<0时,则应用无限次
public static void main(String[] args) { String s = "boo:and:foo"; String[] str = s.split(":",-2); for(int i = 0 ; i < str.length ; i++){ System.out.print(str[i] + " "); } }
结果:
boo and foo
当limit=0时,应用无限次并省略末尾的空字符串
public static void main(String[] args) { String s = "boo:and:foo"; String[] str = s.split("o",-2); for(int i = 0 ; i < str.length ; i++){ if( i < str.length - 1) System.out.print("(" + str[i] + "),"); else System.out.print("(" + str[i] + ")"); } }
结果:
(b),(),(:and:f),(),()
public static void main(String[] args) { String s = "boo:and:foo"; String[] str = s.split("o",0); for(int i = 0 ; i < str.length ; i++){ if( i < str.length - 1) System.out.print("(" + str[i] + "),"); else System.out.print("(" + str[i] + ")"); } }
结果:
(b),(),(:and:f)
