Differences Between Java and C

  In this post I am listing out some differences between Java and C. Of course it does not cover all the differences between Java and C.

• Java is an Object Oriented Programming Language, where as C is a Procedural Programming Language.
• Java does not have the C Keywords sizeof and typedef.
• There are no structures and unions in Java. Consequently the C Keywords struct and union are absent in Java.
• Type Modifiers auto, extern, register, signed and unsigned present in C are not there in Java.
• Explicit pointers are not supported in Java.
• There is no preprocessor for java. So statements like #define, #include etc are absent in Java.
• In Java functions with no argument must be declared with empty parenthesis. In C this can be done by using the void keyword.
• New operators such as >>> and instanceof are added in Java.
• Java supports labelled breaks and continue statements.
• New data types like boolean, reference etc. are added in Java. 
• Many new keywords like private, protected, public etc are added in Java.
