How pointers are used in java?
They aren't. Java uses the (safer) idea of references instead of pointers.
Are gamma rays used in laser pointers?
no , laser pointers emit a lower wavelength of radiation
What are pointers and addresses used for?
To refer to memory.
Why laser mouse are used?
Because the laser pointers are much easier to use than the ball pointers. The ball pointers are often difficult to move around while the laser pointers can move in any direction without "getting stuck"
Do ocular lenses have pointers?
No, ocular lenses do not have pointers. Ocular lenses are used in microscopes and other optical devices to magnify the image for the viewer, but they do not have built-in pointers. Pointer devices are typically separate tools used for indicating or highlighting specific areas of interest in a microscopic sample.
Why pointers in c?
Pointers are variable that are used to point to the address of another variable. OR Pointers can also me defined as variables that are used to store address of another variable. They provide means through which the memory location of variable can be directly accessed and they also support dynamic allocation routines.

Where are array of functions used?
Function Pointers are basically used when we want to select a function which is to be used dynamically at run time.
What are the background pointers in java?
Java does not support pointers.
In C you use the concept of pointers whereas there are no pointers used in JAVA why?
Pointers in C are generally the thing that gives learners the most trouble. When C code is not written correctly with respect to pointer use, the resulting bugs can often be very difficult to find and correct. On the other hand, pointers are absolutely necessary in some cases.The designers of Java wanted to make programming easier and hence avoided adding pointers to the language. Java does have object references which accomplish much of what pointers accomplish albeit in a safer way.
Can you explain the difference between pointers and variables in programming languages?
In programming languages, variables are used to store data values, while pointers are variables that store memory addresses of other variables. Variables directly hold data, while pointers hold the location of where data is stored in memory.
