Jul 17, 2019  If your Java program needs to make a choice between two or three actions, an if, then, else statement will suffice. However, the if, then, else statement begins to feel cumbersome when there are a number of choices a program might need to make. There are only so many else.if statements you want to add before the code begins to look untidy. When a decision across multiple options is required. Message Pop-Ups: JOptionPane Dialog « Swing « Java Tutorial. Java Tutorial; Swing; JOptionPane Dialog; With a message pop-up, there's no return value.

Hi guys

I can't seem to get a new line in a

statement. I try the /n command, but it still doesn't seem to work.

Is there any way I can get a paragraph in a dialog box like this?

Thanks.

Hello all, I'm using the version 6 of Eclipse JAVA development. The code below is very basic, but I'm getting warnings which is probably preventing me from running the application. Any ideas? Basically what I'm designing is a program which would input the radius and therefore it would display the circumference, area, and diameter.

Just updated the code below.
