The largest structure in a java program is a Class. The structure that is the second largest, and a sub-component of a Class is a Method. Each Method has a name and code inside of it that performs a function. Whenever the Method is called upon by naming it the code inside of it is executed. To use a Method in a separate Class requires an Object to be created inside of the separate Class and then the Object is stated along with the Method to be able to perform a Method's specific function.
If the method is defined as static then a class object is not required to call this method.

returnValue = myObject.standardMethod(parameter1, parameter2);

∙ 11y agoAs compared to what? If you use Java, all commands have to be written in methods, so there is really no alternative.

public String getName(){
return this.name;
}
public int multiply(int a, int b){
return a * b;
}

Examples of codes in java?
public class Hello{//opens the classpublic static void main(String args[]){//opens the main methodSystem.out.println("Hello World");}//closes the main method}//closes the classNote: The compiler all the sentences that have "//" before them.
What is function overloading in java?
Any function or method in Java that is coded by the programmer is called a user defined method in Java. The JAVA API (Application Programming Interface) has a set of predefined classes & methods that are for our usage. Whatever methods we create apart from these are termed as user defined methods. In java we not use the term functions. We call them "Methods"
How can i see all the classes and interfaces present in a predefined package in java in command prompt?

Is it possible to override overloaded methods why?
Yes. Overloaded methods are also Java methods and all Java methods can be overridden.

What is the use of api in java?
The API is a reference for all predefined classes provided by the java language. This will allow the programmer to utilize the classes into their programs. The API provides packages, classes, methods, constants, etc.
Why keywords in java important?

No. It is a user defined function which the person who is creating the java class has to code by himself.
What is the use of functions in java?
Same as in other languages. To organize commands into logical pieces. However, in Java the functions are called "methods". This is related to the fact that in Java, methods or functions are defined as part of a class.

Are binary search and linear search already defined method in some class in java and what class is this?
You can check out the Arrays.binarySearch group of methods for searching sorted arrays. There is no predefined linear search for arrays, probably because it is trivially easy to implement. If you have some other data structure to search, the Collections.binarySearch methods should work for you. Most collections can also be converted to a List representation, which has a predefined indexOf method for linear searching.
