Java method of intercepting strings

This article illustrates a Java method for intercepting strings. Share with you for your reference. The specific implementation method is as follows:

public static void main(String args[]) {
  //Begins interception with the first occurrence of this character
  //String str="abc.def";
  //String str="abc.def.sdfsdf.fsdfd.ddddd.ggggg.ttttt";
  //String str1=str.substring(str.indexOf(".")+1, str.length());
  //Begins interception with the last occurrence of the character
  String str="http://wxj.videocc.net/wxj/images/2014/12/i3jwci4j.jpg";
  String str1=str.substring(str.lastIndexOf("/")+1, str.length());
  //Intercepts the next five characters
  // String str="http://wxj.videocc.net/wxj/images/2014/12/i3jwci4j.jpg";
  //String str1 = str.substring(str.length()-5,str.length());
  System.out.println(str1);
}
