Putting 2 strings together

Question

Dear Colleagues
I have a short piece of coding I would hope for some advice on.
public class ReadTest {
public static String readString() throws java.io.IOException {
java.io.BufferedReader in =
new java.io.BufferedReader(new java.io.InputStreamReader(System.in));
return in.readLine();
public static void main(String args[]) {
try {
System.out.println("Enter a string: ");
String inputValue = ReadTest.readString();
System.out.println("You entered: " + inputValue);
} catch (java.io.IOException e) {
System.out.println("An error occurred!");
I have compiled this and was invited on the DOS screen to:"Enter a string". But where do I enter the string?
Then I need to modify the program a little to read two strings and to ensure that the first string ends with the second string. Do I then take it that once I have grasped the fundamentals of joing 2 strings together, that that is the normal rule?
Hopefully, I will begin to understand the code with some help here.
Best wishes

println isnot for user input try the following
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
class KeyView extends JFrame implements KeyListener {
JTextField keyText = new JTextField(80);
JLabel keyLabel = new JLabel("Press any key in the text field.");
KeyView() {
super("KeyView");
setSize(350, 100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
keyText.addKeyListener(this);
Container pane = getContentPane();
BorderLayout bord = new BorderLayout();
pane.add(keyLabel, BorderLayout.NORTH);
pane.add(keyText, BorderLayout.CENTER);
setContentPane(pane);
setVisible(true);
public void keyTyped(KeyEvent input) {
char key = input.getKeyChar();
keyLabel.setText("You pressed " + key);
public void keyPressed(KeyEvent txt) {
// do nothing
public void keyReleased(KeyEvent txt) {
// do nothing
public static void main(String[] arguments) {
KeyView frame = new KeyView();
