Creating text string on mouse click in Java-Swing?

Question

Using swing, trying to make the text "Mouse is Clicked" appear on the screen for 2 seconds whenever I click the mouse.

This is what I have so far.

String s = "";
int timeDelay = 30;
public void paintFrame(Graphics g) {
        g.drawString(s, 100, 100);

        if (timeDelay>0) {
            timeDelay--;

        }

        if(isMouseClicked()) {
            String s = "Mouse is clicked";
            timeDelay = 30;
            return;
        }

        String s = "";
}

Nothing is showing up when I click, can't seem to figure out why.

Answer 1

You need to call g.drawString() inside if condition for isMouseClicked(). Also inside the if condition for isMouseClicked() you are creating a new local parameter String s(not sure if you want to do that). You cna try the following piece of code.

 if(isMouseClicked()) {
        s = "Mouse is clicked";
        timeDelay = 30;
        g.drawString(s, 100, 100);
  }
 else{
      s = "";
 }
 g.drawString(s, 100, 100);

If it's not disappearing for whatever reason, you could use the tertiary operator for a quick fix. Set's the string depending on the isMouseClicked() boolean

s = isMouseClicked() ? "Mouse is clicked" : "";
g.drawString(s,100,100);
