In Java:
You declare the variable like this:
int sum;
If you want to include decimals, change this to:
double sum;
To store an initial value, just use the assignment operator:
sum = 0;
You can combine this with the declaration:
double sum = 0.0;
To add something to the variable, for example the value of a variable called "x", use one of the following:
sum = sum + x;
sum += x;

if u declare variable in method & tray to use this variable outside the method then it is out of scope
A variable declared as final can't be modified, once a value is assigned.
native is a key word used in java method. there is no variable as native in java
In Python, you declare a variable by simply assigning a value to a name, like x = 10. In Java, you need to specify the type, such as int x = 10;. In JavaScript, you can use let x = 10;, const x = 10;, or var x = 10;, depending on the scope you need. In C++, you would declare a variable with a type as well, like int x = 10;.
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

You declare a variable the same in a JSP as you do in a servlet. Let's say you want to declare a String variable called "foo" and you wanted to assign it a value of "bar." You would do this: String foo = "bar"; Of course, in a JSP, any Java code needs to be enclosed within <% and %>.
With the command return, followed by an object variable. In the method header, you have to declare the return type as the class of the object.

The "uno" keyword is used in programming languages like Java to declare a variable that can only be assigned a value once. This helps ensure that the variable's value remains constant throughout the program.

There is no separate entity as a static object in java. The static keyword in java is used to signify that the member (either a variable or a method) is not associated to an object instance of the class. It signifies the fact that the member belongs to the class as a whole. The words static and objects are opposites of one another so you cannot have a static object. However, you can declare an object as a class level variable which could be referred to as a static object but it will be referred to as a static or class variable and not a static object.
There's no global variables in Java.
int
yes we can define a variable in an interface in java.
