Why in a Java program that asks for user input the blinking cursor is not positioned where it should be.

Look at this code:

public class GettingInput
{
   public static void main(String args[])
   {
	   int x;
	   int y;
	   
	   Scanner in = new Scanner(System.in);
	   
	   System.out.print("Enter a number: ");
	   x = in.nextInt();
	   
	   System.out.print("Enter another number: ");
	   y = in.nextInt();
	   
	   int sum = x + y;
	   
	   System.out.println("Sum is " + sum);
   }
}

When I run the program the blinking cursor is never where it should be. Seems to me it should be after the word number: cursor should be here.

But I can never get it there.

Is there something I'm doing wrong when I run my program or is this just a Java quirk?

So where does it happen to be? That works perfectly fine in my case, I ran your code in NetBeans and the following was the output,

run:
Enter a number: 55
Enter another number: 45
Sum is 100
BUILD SUCCESSFUL (total time: 14 seconds)

You can see "55" comes right after "number: " and so on for the next line. The question is which compiler are you using, or what IDE is being used? print must never add "\n" to the output, if that is happening, change the compiler.

I'm using Eclipse Mars. When I run the program it first shows Enter an integer: with no cursor being shown. I then enter a number and then hit Enter and then what happens is it shows Enter an integer: the second time around but the cursor shows up before the Enter an integer:

It's just dumb.

Why doesn't the cursor automatically get placed after the Enter an integer:

Just annoys me. I'm using Eclipse Mars with whatever compiler the JDK ships with.

That sounds more like an issue with your PC or console settings.

Not a computer issue. Many people have reported the same thing across the Web.

I Googled for that and did not find any references that match your problem.

Can we merge multiple PPTX files into single file using JAVA ?

How do we work on the analysis of the periods of ECG ,example Qr alone, and so, therefore, to be compared with the original signal using java .

Learning Java, reading:
"Java the Complete Reference", Ninth Edition

This is regarding JavaFX.

Writer's code:
ImageView hourglassIV = new ImageView("hourglass.png");
Label hourglassLabel = new Label("Hourglass", hourglassIV);
rootNode.getChildren().add(hourglassLabel);

My Code:

Label hourglass = new Label("Hourglass", new ImageView("hourglass.png"));
rootNode.getChildren().add(hourglass);

Is my code okay, or should I write it like the book Writer's code?

In respect to accepted Java coding guidelines.
My code works.

I'm a programmer in another language converting to Java and want to do it right.
