Need help changing Main to allow user input using scanner class:public class GUIparser {

//Creates the class’ constructor

private static Scanner scnr;

private static File inp_file;

private static String getLabel(String file_lines) {

;

int cntr;

file_lines.trim();

for (cntr = 0; cntr < file_lines.length(); cntr++) {

char tmp=file_lines.charAt(cntr);

boolean b2 = Character.isLetter(tmp);

if (!b2){

break;

}

}

return file_lines.substring(0, cntr);

}

public static void main(String[] args) {

String strng, lbl;

try{

inp_file = new File(“Input.txt”);

scnr = new Scanner(inp_file); //Reads from the file

if (scnr.hasNextLine()) {

strng = scnr.nextLine().trim();

lbl = getLabel(strng); //Get the componenent label

if (!lbl.equalsIgnoreCase(“Window”)) {

System.out.println(“First label should be WINDOW”); //If the window is not labelled

return;

}

strng = strng.substring(lbl.length()).trim();

JFrame frame = (JFrame) addCompntRec(strng, lbl);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

}

else{

System.out.println(“Unknown Error”);

}

}

catch (FileNotFoundException exp){

System.out.println(“File not found”); //If the file is not found

exp.printStackTrace();

}

catch (Exception excep) {

System.out.println(“Unknown Error”);
