Hello,

how to ask for inputs again after the program terminate? it doesn't ask for the angle input to restart after the system terminate? How to fix it? this is java

I want it to terminate first then restart

if (error < 0) { if (launchAngle == 45) { JOptionPane.showMessageDialog(null, "Target is too far! Restart the program with greater initial velocity!", "Modification needed", JOptionPane.WARNING_MESSAGE); System.out.println("Target is too far!\ Restart the program with greater initial velocity!"); } else { JOptionPane.showMessageDialog(null, "Restart the program with greater initial angle as 45!", "Modification needed", JOptionPane.WARNING_MESSAGE); } System.exit(0); angleInput = JOptionPane.showInputDialog("Enter the launch angle in degrees:"); flightTime = 2 * initialVelocity * Math.sin(radian) / GRAVITATION; flighttimeDivided = flightTime / 2; highestPoint = (initialVelocity * Math.sin(radian)) * flighttimeDivided - (double) 1 / 2 * (GRAVITATION * Math.pow(flighttimeDivided, 2));// not 94.53 distanceTraveled = (initialVelocity * Math.cos(radian)) * flightTime; error = distanceTraveled - distanceToTarget; minError = Math.abs(error); trajectory = String.format( "initial velocity: %.1f feet/sec launch angle: %.1f degrees flight time: %.2f seconds maximum height: %.2f feet distance traveled: %.2f feet target missed: %.2f feet", initialVelocity, launchAngle, flightTime, highestPoint, distanceTraveled, error); title = "Trajectory data report"; JOptionPane.showMessageDialog(null, trajectory, title, JOptionPane.INFORMATION_MESSAGE); trajectory = String.format( "initial velocity: %.1f feet/sec launch angle: %.1f degrees flight time: %.2f seconds maximum height: %.2f feet distance traveled: %.2f feet target missed: %.2f feet", initialVelocity, launchAngle, flightTime, highestPoint, distanceTraveled, error); System.out.println(trajectory);
