looping for specified amount of time
A Simple program i made has a text box were you specify the number of times to make the loop, a text box of the text to display in the loop and this is displayed in a JTextArea. It might be easer if i post the code:
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import java.util.*;
public class LoopApplet extends JApplet implements ActionListener
{
JButton perform;
JLabel timesLabel;
JLabel textLabel;
JTextField txtNumOfTimes;
JTextField txtText;
JTextArea message;
public void init()
{
Container pane = getContentPane();
FlowLayout flo = new FlowLayout();
pane.setLayout(flo);
JPanel row1 = new JPanel();
timesLabel = new JLabel("# of Times");
row1.add(timesLabel);
txtNumOfTimes = new JTextField(15);
row1.add(txtNumOfTimes);
pane.add(row1);
JPanel row2 = new JPanel();
textLabel = new JLabel("Text :");
row2.add(textLabel);
txtText = new JTextField(15);
row2.add(txtText);
pane.add(row2);
JPanel row3 = new JPanel();
perform = new JButton("Perform");
perform.addActionListener(this);
row3.add(perform);
pane.add(row3);
JPanel row4 = new JPanel();
message = new JTextArea(5,15);
message.setLineWrap(true);
message.setWrapStyleWord(true);
JScrollPane scroll = new JScrollPane(message, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
row4.add(scroll);
pane.add(row4);
setContentPane(pane);
setVisible(true);
}
public void actionPerformed(ActionEvent e)
{
String num = txtNumOfTimes.getText();
int numTimes = Integer.parseInt(num);
String text = txtText.getText();
String source = e.getActionCommand();
try {
for (int x=0; x<numTimes; x++)
{
message.append(x + " " + text + "\n");
}
} catch (NumberFormatException nfe)
{
txtText.setText("NumberFormatException");
}
}
I want to change the code in the actionperformed event so that it loops for an amount of time(what the user inputs in the textbox) but i have failed every time i try this. I know how to loop for a given amount of time but not sure how to apply it to this. Here is an example of looping for 1minute.
Code:
import java.util.*;
class Repeat {
public static void main(String[] arguments) {
String sentence = "poop";
int count = 1;
Calendar start = Calendar.getInstance();
int startMinute = start.get(Calendar.MINUTE);
int startSecond = start.get(Calendar.SECOND);
start.roll(Calendar.MINUTE, true);
int nextMinute = start.get(Calendar.MINUTE);
int nextSecond = start.get(Calendar.SECOND);
while (count < 1000000) {
System.out.println(sentence);
GregorianCalendar now = new GregorianCalendar();
if (now.get(Calendar.MINUTE) >= nextMinute)
if (now.get(Calendar.SECOND) >+ nextSecond)
break;
count++;
}
System.out.println("\nDisplayed " + count
+ " times. ");
}
}
How could i make this into my program??????????
