String[] split = data.split("\\|",-1);
This is not the actual requirement in all the time. The Drawback of above is show below:
Scenerio 1:
When all data are present:
String data = "5|6|7||8|9|10|";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 7
System.out.println(splt.length); //output: 8
When data is missing:
Scenerio 2: Data Missing
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output: 8
Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output:7
What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.
