Set multiple system properties Java command line

Question

Is there an easier way to specify multiple System Properties on the command line to a Java program rather than having multiple -D statements?

Trying to avoid this:

 java -jar -DNAME="myName" -DVERSION="1.0" -DLOCATION="home" program.jar

I thought I had seen an example of someone using one -D and some quoted string after that, but I can't find the example again.

Answer is NO. You might have seen an example where somebody would have set something like :

-DArguments=a=1,b=2,c=3,d=4,e=cow

Then the application would parse value of Arguments property string to get individual values. In your main you can get the key values as(Assuming input format is guaranteed):

String line = System.getProperty("Arguments");
if(line != null) {
  String str[] = line.split(",");
    for(int i=1;i<str.length;i++){
        String arr[] = str[i].split("=");
        System.out.println("Key = " + arr[0]);
        System.out.println("Value = " +  arr[1]);
    }
}

Also, the -D should be before the main class or the jar file in the java command line. Example : java -DArguments=a=1,b=2,c=3,d=4,e=cow MainClass
