  How to splice a string in java
  
  So if I have a string such that
  String name = "Daniel";
  int age = 18;
  
  If I want to create a string username using for example the first 3 letters of the name + the age, how can I manipulate the name to get the first 3 letters?
  I understand that you can do the string.split() but I don't understand how this is applicable to this scenario. 
  I'm sorry if this is a stupid question but as you can probably tell I'm still a noob. Thanks in advance
  
  A:
  
  String username = name.substring(0, 3) + String.valueOf(age);

  you should take a look at the substring method. here's an example:
  String myString = "this is a test string";
  String subString = myString(0 /* begin index included letter*/, 4 /* end index excluded letter */) => // subString is now "this"
  
  in your case it would look like that:
  public static String extractInfos(String name, int age) {
      if (name.length() >= 3) {
          return name.substring(0, 3) + String.valueOf(age);
      }
      return name + String.valueOf(age);
  }
  
  // test section
  String name = "Daniel";
  int age = 18;
  extractInfos(name, age); // outs "Dan18"
