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)
