Question

How to extract hours, minutes and second from string in Java

Answer 1

import java.util.ArrayList;

public class MyClass {
    public static void main(String args[]) {
        String str = "11:58:35";

	    ArrayList<String> time_parts = new ArrayList<String>();
	    int pos = 0;

	    while ((pos = str.indexOf(":", pos)) != -1) {
		    time_parts.add(str.substring(0, pos));
		    str = str.substring(pos + 1);
	    }
	    time_parts.add(str); // Add the seconds

    	if (time_parts.size() != 3) {
		    System.out.println("Invalid time format");
	    }

	    int hours = Integer.parseInt(time_parts.get(0));
	    int minutes = Integer.parseInt(time_parts.get(1));
	    int seconds = Integer.parseInt(time_parts.get(2));

	    System.out.println(hours + ":" + minutes + ":" + seconds);
    }
}
