What is the executable method in java?
In Java, the executable method is the main method, which serves as the entry point for any standalone Java application. It is defined as public static void main(String[] args), where String[] args allows for command-line arguments to be passed to the program. The main method must be declared as public and static, and it returns no value (void). When a Java program is run, the Java Virtual Machine (JVM) looks for this method to start the execution of the program.
Differences between pass by value pass by reference in java?
pass by value is the technique where a copy of the variable is passed to the method as argument. This value can be modified inside the method but that would not affect the original value. Pass by reference is the technique where the reference to the actual variable is passed to the method as argument. Any changes to this variable would affect and alter the original value. Usually primitive data types are passed by value and objects are passed by reference in java.

What is the use of the parameter in java?
A parameter is a variable that is passed to a method. It is not specific to Java, and is used in almost all programming languages. The parameter is used by the method in whatever way that it wants. Example: public void add(int x, int y) { return x + y; } In this case, the parameters are two integers, x and y. They are passed to the method 'add' which returns the sum of the parameters.
How does java pass primitive types and objects?
Java uses only pass by value. Primitive data types are passed purely as pass by value whereas for objects a value which is the reference to the object is passed. Hence the whole object is not passed but its reference gets passed. All modifications to the object in the method would modify the object in the Heap.
