________________________
id = Integer.parseInt(array[0]);
name = array[1];
payRate = Double.parseDouble(array[2]);
gross = payRate * HRS_IN_WEEK;
System.out.println("ID#" + id + " " + name +
" $" + payRate + " $" + gross);
total += gross;

}

System.out.println(" Total gross payroll is $" + total);
}
}
The above code demonstrates a retrieved file where Strings are split into usable fields. In the blank line provided, write a String class split() method to split the String s that accepts an argument that identifies the field delimiter (in this example, a comma) and returns an array of Strings. The result should be assigned to the String[] array.
