Assuming each line will always have the format in your sample data above, then you can simply split each line of the text file and retain the second string: Output:

APIzation

String line = "name: brayn birthday: 1994";
String[] parts = line.split(" ");

String name = parts[1];
System.out.println(name);
brayn

package com.stackoverflow.api;

public class Human36110491 {

  public static String getNameFromLine(String line) {
    String[] parts = line.split(" ");

    String name = parts[1];
    //System.out.println(name);
    return name;
  }
}
