Test.java source code is :
import javutil.Properties;
class Test {
public static void main (String[] args){
Properties p = System.getProperties();
System.out.println(p.getProperty("key1"));
}
}
you have issued below commands from command prompt.
cd javaproject
java -D key1=value1 Test
What is the output ?
