[xyliew25]

How to test

1. Select the Java language.

2. Input syntactically valid and well-typed Java programs into the code editor - a simple one like the one below or more interesting ones from java-slang/src/ec-evaluator/__tests__

   class Test {
       public static void main(String[] args) {
           int x = 1;
       }
   }
