There is no concept similar to pointers in Java. Pointers are a feature in C Programming using which a programmer can access the memory. This was the cause of major catastrophic programming bugs. The creators of Java excluded this feature just to avoid such catastrophic bugs.

∙ 12y agoPointer is strictly avoided in java.
because, java runs under JRE (Java runtime environment) which always have some memory allocated to it for execution of program , when we use pointer it is possible that ,this pointer variable use memory outside of JRE then this will cause an error which is undefined.
so pointer is not useful in java

No,Java does not support pointer. A pointer is a variable which can hold the address of another variable or object. there is no any concept for pointer in java which makes java robust.

Java null pointer exceptions?
A null pointer exception in java comes when you are trying to perform any action on an object that isnt initialized/has a value i.e., is a NULL Value Ex: private String s; //declare a string if(s.equals("test")){ //do something.. } You will get a null pointer in the if condition because you are checking a value that is null which is not allowed..

How does java secures the code?
java is securejava uses the pointer internally. programer cannot use the pointer in our program explicitly. due to use of pointers information may be lostex-int *p;int a=56;int b=98;p=&a;p=&b;in above program first time pointer points the a value and in next line p points the b value, so here a information is lost
Where string is stored on Heap or Stack in java?
A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.A String is treated as an object, meaning there is an object on the heap.

What is difference between constant in c plus plus and final in java?
The final keyword can be used to modify a class, method, or variable.When used on a variable, it means that variable cannot be changed once set.When used on a method, it means that no subclasses may override that method.
Explain the importance of this keyword in java?
this is treated like a pointer to the object it's written in. It's important if you want to call a method with the object calling it as an argument, or something like that.
