Displaying loop horizontally in jlabel

while (minValue <= maxValue){
        valueOutput.setText(""+minValue);
        minValue++;

This is the while loop that I'm using to display the numbers from an entered minimum and maximum number, but I am having trouble displaying the numbers properly in the jLabel

The numbers are formatted vertically and only shows the last number in the jLabel

The setText() replaces the existing text.

What you want to do is create a String in your loop and when the loop finishes you set the text in the label with the text in the String. You can use the StringJoiner class for this:

StringJoiner sj = new StringJoiner(",");

while (minValue <= maxValue)
{
    sj.add( "" + minValue);
    minValue++;
}

valueOutput.setText( sj.toString() );

Try this:

StringJoiner joiner=new StringJoiner();

while (minValue <= maxValue){
   joiner.add(String.valueOf(minValue++);
}
valueOutput.setText(joiner.toString());

This will create string of numbers separated by default separator (,) and then it will pe placed inside label (assuming thats what valueOutput is )

You can replace StringJoiner with StringBuilder if you are not using Java8
