Class JavaPropExtractGenerator

java.lang.Object

net.covers1624.jdkutils.utils.JavaPropExtractGenerator

public class JavaPropExtractGenerator
extends java.lang.Object

Generates a class which echos all the provided program arguments as system property Key-value pairs to the program's standard output.

     public static void main(String[] var0) {
         PrintStream var1 = System.out;

         for(int var2 = 0; var2 < var0.length; ++var2) {
             var1.print(var0[var2]);
             var1.print("=");
             var1.println(System.getProperty(var0[var2], ""));
         }
     }
 

When invoked with the following arguments "java.version" "java.vendor" the following standard output is generated:

     java.version=1.8.0_292
     java.vendor=Oracle Corporation
 

Whilst this class requires Objectweb ASM, it is only required when re-generating the PropExtract class.
