## SIZ EDUCATION ||Functions in Java ||By @mohsin444

I am well and i hope you are all well and good.Today i thought that i give all information about functions in Java.

Functions in Java

In Java, all feature definitions should be internal classes. We additionally name features techniques. Let's study an instance technique.


source

foo is a way we described in elegance Main. Notice some matters approximately foo:

Static approach this technique belongs to the elegance Main and now no longer to a selected example of Main. Which approach we will name the technique from a distinct elegance like that Main.foo().

Void approach this technique does not go back a price. Methods can go back a unmarried price in Java and it needs to be described withinside the technique declaration. However, you could use go back with the aid of using itself to go out the technique.

This technique does not get any arguments, however of route Java techniques can get arguments as we will see in addition on.

Arguments

I constantly like to mention that arguments to Java techniques are handed with the aid of using price, even though a few would possibly disagree with my preference of words, I locate it the excellent manner to provide an explanation for and recognize the way it works exactly.

By price approach that arguments are copied whilst the technique runs. Let's study an instance.

source

Here is a any other region withinside the code, wherein bar is called

int a = 3;
int b = 5;
bar(a, b);

You can photo on your head that after bar(a, b) is run, it is like withinside the starting of bar the subsequent strains are written:

int num1 = a;
int num2 = b;

And simplest then the relaxation of the technique is run.

*This approach that a price get copied to num1 and b price get copied to num2. Changing the values of num1 and num2 will now no longer have an effect on a and b.

*If the arguments have been gadgets, the guidelines continue to be the identical, however it acts a piece differently. Here is a an instance:

source

Again we will photo the identical strains withinside the starting of bar2

Student s1 = joe;
Student s2 = jack;

*But whilst we assign gadgets, it is a piece distinct than assigning primitives. s1 and joe are distinct references to the identical item. s1 == joe is proper. This approach that going for walks techniques on s1 will alternate the item joe. But if we will alternate the price of s1 as a reference, it's going to now no longer have an effect on the reference joe.

s1.setName("Chuck"); // joe call is now Chuck as well
s1 = new Student("Norris"); // s1 is a brand new student, distinct than joe with the call of Norris
// s1 == joe isn't proper anymore.

Non Static Techniques

source

Non static techniques in Java are used extra than static techniques. Those techniques can simplest be run on gadgets and now no longer at the entire elegance.

Non static techniques can get right of entry to and adjust the sector of the item.
