    @user7722867 Won't work. The pipe is a special character in regex. – MC Emperor Mar 22 '19 at 11:12

You can use the split function. This will return your string split into the parts, seperated by |.

var result = "HEADER|INPUT|2017|test|1 |Id|Name|".split("\\|");
// Access an array
// result[0] will be 'Header'

You can use String.split() function:

String string = "HEADER|INPUT|2017|test|1 |Id|Name|";
String[] parts = string.split("\\|");
String part1 = parts[0]; // HEADER
String part2 = parts[1]; // INPUT
String part3=parts[2]; //2017

and so on.

You can make use of split() method here to divide your string as per your requirement.

String input= "HEADER|INPUT|2017|test|1 |Id|Name|";
String[] contents = input.split("\\|");
String name = input[6]; 
String id = input[5]; 
String number = input[4]; 
String test = input[3];  
String year = input[2];  
String input = input[1]; 
String header = input[0];
