Java is known to be a strongly type safe language, but there are some coding conventions and when these are used in some applications like persistent storage through serialization may generate unreliable or wrong output. Such cases should be caught and modified as per requirement to produce a modified safe program. This can be achieved by designing a translator tool which can catch unsafe code segments and produce a modified safe code segment. When a singleton class is serialized it is necessary to include a special method from serializable interface within it then only it gives us right result. If this method is not there within the class then it produces unpredictable results. Such results may violate type safe property of object oriented programming. Here the translator is designed using ANTLR which is going to check availability of this method in the input java file. If this method is not found then add the method and generate a type safe program at output. The same translator can be applicable for generics and their limitations. Here the translator is going to trace if there are any unchecked warnings or runtime exception then modify the input program to generate a safe program at output. This will lead to minimize limitations of java generics.
