Splitting String delimited using pipe(|) symbol - Java code

public class SplitString {
  public static void main(String[] args) {
    String str = "A001|BOA|Ronda|5000";
    String[] data = str.split("\\|");
    System.out.println("Name- " + data[2]);
  }
}

public class SplitString {
  public static void main(String[] args) {
    String str = "A001	BOA	Ronda	5000";

    System.out.println("Amount- " + data[3]);

    String str = "A001  BOA Ronda 5000";
    // Matches any number of spaces
    String[] data = str.split("\\s+");
    System.out.println("Amount- " + data[3]);
  }
}
