Thread: newbie start java program with switches

You can do it like this:

public class ProgramArguments {
 
	/**
	 * JavaProgrammingForums.com
	 */
	public static void main(String[] args) {
 
		if(args.length < 1){
			System.out.println("No argument");
		}		
		else if(args[0].equals("-d")){
			System.out.println("Decrypt Method");
		}
		else if (args[0].equals("-e")){
			System.out.println("Encrypt Method");
		}
	}
}

This is just an example.

java -jar ProgramArguments.jar -d

 

Decrypt Method

args[1] password
args[2] input.txt
args[3] output.txt

ok say for instance i wanted to check if the password part of the starting argument was happy would i look in args[1] for example

 if (args[1].equals("password1234")){
 
veriffy password ect ect 
 
}

becasue i need to run the password through an algorythum to verify if it is correct or not



and the text files would be ars [2] abd args[3]


also do you know how i can use netbeans to run the java application wth the arguments ???

EDIT: I FOUND OUT HOW Netbeans IDE Blog by Tushar Joshi, Nagpur: Using Command Line Arguments in NetBeans IDE

Yes args[1] would be the password string

Glad you found out how to run command line arguments with Netbeans.

If you ever use Eclipse, you can do the same thing like this:
