How to run a Java program in Visual Studio

[NovaGear G2]

I'm trying to run my old Java code in Visual Studio and I installed the Java Language Support extension but when I try to run it, the command window quickly opens and closes. It does it in a flash so I don't know what the output even looks like. Is there a Java equivalent to C++'s System("pause"), is there some settings I need to configure? What can I do to make VS my Java IDE?

If your running it in debug config just use a break point. I don't know enough about java to give a very detailed answer.

Sadly, there isn't a simple built-in function in Java to achieve this. You'll need to make one using the scanner and nextLine(). An example being...

 

//You can put this where-ever appropriate, so long as it's in the right scope
Scanner input = new Scanner()

//Asks for user input before continuing
void PauseForUser()
{
	System.out.println("Press any key to continue");
    input.nextLine();
}

It's not perfect, but it'll do in a pinch.

Breakpoints work in debug mode like trag1c suggested, but you can also run without debugger and it won't close the console window on you. At least it works that way for .NET console apps.

 

How good is VS for Java development anyway? I assume it's ok but the extension page says

This extension is not meant to replace a full IDE, but has certainly helped when I wanted to quickly reference a Java source file while working within Visual Studio.

Seems to me like you'd be better off using a proper Java IDE like IntelliJ.
