What are the difference between main and void main void?
The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data. When our program is simple, and it is not going to terminate before reaching the last line of the code, or the code is error free, then we can use the void main().
What is the difference between public static void main and static public void main?
public − This is the access specifier that states that the method can be accesses publically. static − Here, the object is not required to access static members. void − This states that the method doesn’t return any value.
What is a static void main?

What is difference between ++ A and A ++?
++a returns the value of an after it has been incremented. It is a pre-increment operator since ++ comes before the operand. a++ returns the value of a before incrementing.
Why Getch is used in C?
Why we use a getch() function? We use a getch() function in a C/ C++ program to hold the output screen for some time until the user passes a key from the keyboard to exit the console screen. Using getch() function, we can hide the input character provided by the users in the ATM PIN, password, etc.
What is the difference between static and void?
static means that the method is associated with the class, not a specific instance (object) of that class. This means that you can call a static method without creating an object of the class. void means that the method has no return value.
What is the difference between public void and private void?
public means that the method is visible and can be called from other objects of other types. Other alternatives are private, protected, package and package-private. void means that the method has no return value. If the method returned an int you would write int instead of void.
Why java main method is static and void?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class. In any Java program, the main() method is the starting point from where compiler starts program execution. So, the compiler needs to call the main() method.
Why we use static void main in java?
When java runtime starts, there is no object of the class present. That’s why the main method has to be static so that JVM can load the class into memory and call the main method. If the main method won’t be static, JVM would not be able to call it because there is no object of the class is present.
What is the difference between and ==?
The ‘==’ operator checks whether the two given operands are equal or not….What is the difference between = (Assignment) and == (Equal to) operators.
| = | == |

| It is used for assigning the value to a variable. | It is used for comparing two values. It returns 1 if both the values are equal otherwise returns 0. |
What is difference between a ++ and ++ A?
++a returns the value of an after it has been incremented. It is a pre-increment operator since ++ comes before the operand. a++ returns the value of a before incrementing. It is a post-increment operator since ++ comes after the operand.
