Java字符串分割函数split用法

下面的代码简单演示了java中字符串分割函数split的用法

语法如下

public String[] split(String regex, int limit)

or

public String[] split(String regex)

范例演示

import java.io.*;

public class Test{
   public static void main(String args[]){
      String Str = new String("Welcome-to-Tutorialspoint.com");

      System.out.println("Return Value :" );
      for (String retval: Str.split("-", 2)){
         System.out.println(retval);
      }
      System.out.println("");
      System.out.println("Return Value :" );
      for (String retval: Str.split("-", 3)){
         System.out.println(retval);
      }
      System.out.println("");
      System.out.println("Return Value :" );
      for (String retval: Str.split("-", 0)){
         System.out.println(retval);
      }

      System.out.println("");
      System.out.println("Return Value :" );
      for (String retval: Str.split("-")){
         System.out.println(retval);
      }
   }
}

返回结果如下
