A variable is something that can store data, such as numbers and words. One of the common types of variables is called "int", which can store numbers.
Creating a variable is simple:
int myVar;
"int" is the data type of the variable, and "myVar" is the name of the variable, you can choose almost any name you want for your variables.
Then you can assign a number to this variable, you can even use negative numbers:
myVar = 5;
Notice how you do not need to type "int" again, you only need to do it once when you create the variable.
Here's how to add numbers to variables:
myVar = myVar + 4;
OR
myVar += 4;
When you do either of these it will add 4 to the value of myVar, which means myVar now equals 9. (5 + 4 = 9)
You can also use subtraction: -
Multiplication: *
Division: /
and Modulus: %
Another imortant data type is the String, a String can store words and letters, and behaves much like an int.
String myVar;
myVar = "Hello";
myVar += " there, Sir.";
Now, like we did with the int earlier, myVar equals "Hello there, Sir."
One last thing, you can add different variables together, but they must be the same data type:
myVar += anotherVar;
native is a key word used in java method. there is no variable as native in java
A Variable that is shared as well as synchronized cannot be created in Java. These two terms are mutually exclusive and a variable that is synchronized in java cannot be shared and vice versa
yes we can define a variable in an interface in java.
Ideal thing would be to retrieve the value from PHP using AJAX and then assigning it to a java script variable. Thereafter compare it to the java script variable that is already present.
Yes. You can have as many variables as you want in Java
native is a key word used in java method. there is no variable as native in java
A Variable that is shared as well as synchronized cannot be created in Java. These two terms are mutually exclusive and a variable that is synchronized in java cannot be shared and vice versa
There's no global variables in Java.

yes we can define a variable in an interface in java.
There are several different methods to convert an integer variable to a string variable in Java. For example, one can use the following code to convert an integer variable to a string variable: Integer.toString(number)

Yes. You can have as many variables as you want in Java
That refers to a variable attached to an object - also known as a field.
a method is a variable
variable_name=variable_name+5;
I suppose you want to ask about variable initialization.Java initialize its variables in its constructor.
