What is caller ?

by

Same as caller principal.

In the context of advanced Java programming, the term “caller” typically refers to the entity or part of code that invokes or calls a method or function. When you have a method or function in your program, the part of the code that makes a call to that method is referred to as the “caller.”

For example, consider the following Java method:

java
public class Example {
public void myMethod() {
// Some code here
}
}

If you call this method from another part of your code like this:

java
public class AnotherClass {
public static void main(String[] args) {
Example example = new Example();
example.myMethod(); // The part of code making the call is the "caller."
}
}

In this scenario, the main method in the AnotherClass class is the caller, as it is calling the myMethod method of the Example class.

So, in summary, the “caller” in advanced Java programming is the part of the code that makes a call to a method or function.
