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

结果:

结果:
