◕ Why should we declare the initial value of a variable in Java?
It is a very good practice to always initialize our variables when we declare them.
If we declare the initial value of a variable in Java then we can avoid so many problems as shown bellow.
- 1) The variable cannot take a junk value left over from when the memory was last used.
- 2) Sometimes if we try to use a variable in a calculation that has not had a value assigned to it, then our program does not compile.
It causes a problem and takes lot time to debug.
- 3) Sometimes the compiler cannot determine whether or not a variable has been initialized before it is used if we don't initialize it.
This shows an error again and again while running the program.
