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)
