How to define a char stack in java? For example, to create a String stack I can use such construction:
Stack <String> stack= new Stack <String> ();
But when I'm try to put char instead String I got an error:
Syntax error on token "char", Dimensions expected after this token
To use stack in C++ we have to include teh header file #include <stack> and then we can define stack of any type using the format stack <TYPE> name; for example : stack <int> s1; will create an integer stack s1 . stack <char> s2; will create a character stack s2 .
Stack<Character> myStack = new Stack<Character>(); char letter = 'a'; myStack. push((Character) letter); Create a stack that contains Character objects, and cast your char s to Character before you insert them. Just like int s and Integer s, you need to wrap a primitive before you can insert it in to a data structure.
The char keyword is a data type that is used to store a single character. A char value must be surrounded by single quotes, like 'A' or 'c'.
Primitive types such as char
cannot be used as type parameters in Java. You need to use the wrapper type:
Stack<Character> stack = new Stack<Character>();
char
is one of the primitive datatypes in Java, which cannot be used in generics. You can, however, substitute the wrapper java.lang.Character
, as in:
Stack<Character> stack = new Stack<Character>();
You can assign a Character
to a char
or the other way around; Java will autobox the value for you.
