DataStructure in Java works same as in C language?
1. LinkedList,Binary tree, Queue,Stack, only thing all are built-in classes in java.we need to decide which one to use and all.
But internally works same as learnt in C language?
They work according to what their docs say they do, which is pretty much in accordance with how those types are described to behave in a data structures text book. Similarly named data structures in C will behave similarly, if they're written correctly.
As for "internally," if you mean how they're implemented, then that is not specified. Each Java version or implementation could be different from the others, and they could all be very different from C. In fact it's guaranteed that they'll be different from C to some extent. But the general structure and flow will probably be pretty similar among most implementations.
