I took a Java class last semester. We never got to the chapter on GUI's but I'd like to start making them. I just want to add a text field and a label next to it that says "Hourly Wage".

Also, when I run this in Xcode, it reports back with "Shell Script Invocation Error" "Command usr/bin/java failed with exit code 1".

Here's my program:

package summerIncome;

import java.util.Scanner;

public class SummerIncomeCalculator {

public static void main(String[] args) {

jFrame frame = new Jframe("Summer Income Calculator");

frame.setSize(400,300);

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

add(new JTextField("Income in dollars per hour");

Scanner input = new Scanner(System.in);

System.out.println("Enter hourly wage:");

double hourly = input.nextDouble();

//Pre-tax income

double weekly = hourly * 40;

double total = weekly * 10;

System.out.println("Summer earnings before tax are " + total);

//Tax deductions

double tax = total * .10;

double tax2 = tax * .3;

double tax3 = tax2 * .765;

double total2 = total - tax3;

System.out.println("Total Summer earnings after tax are $ "

+ total2);

input.close();

}

}
