How to convert string to int in array

Im trying to read a line of file that has words and numbers in it and save it into a array

The file reads:

Barrett Edan 70 45 59

Part of the code that has a problem:

** let it be known that field was declared as a string array earlier in the code**
String [] fields = new String[100];
int [] numfields = new int[100];

while (reader.hasNext()) {     //while reader reads a line
  line = reader.nextLine();  //line reads reach line of file
  fields = line.split("\t");  //splits line by tab space and saves it into fields
  
  last[count] = fields[0];   // saves first word to first element of array
  first[count] = fields[1]; //saves second word to second element
  numfields[0] = fields[2]; /* THE PROBLEM: now i expected the 3rd word (70) of fields to be able to save into numfields array , but thats when i get cannot be converted to int error
  numfields[1] = fields[3];
  numfields[2] = fields[4];    */

>Solution :

You have to explicitly convert from String to int. Java will not do this for you automatically.

numfields[0] = Integer.parseInt(fields[2]);
// and so on...

Presumably this line of data pertains to a single "thing" in whatever problem you’re working on. Parallel arrays area bad habit to get into. Rather you want one array/list/whatever composed of objects which hold all of the data pertaining to a single "thing."
