Java split usage and example code _java

Public string[] Split (String regex) default limit is 0

Public string[] Split (String regex, int limit)

When Limit>0, the n-1 time is applied

public static void Main (string[] args) {
    String s = "Boo:and:foo";
    string[] str = s.split (":", 2);
    System.out.print (Str[0] + "," + str[1]);
 }

Results:

Boo,and:foo

When limit<0, unlimited times are applied

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] + "");
    }
 

Results:

Boo and Foo

When limit=0, apply an infinite number of times and omit the empty string at the end

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] + ")");
    }
 

Results:

(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] + ")");
    }
 

   

Results:

(b), (), (: And:f)
