int keyword in java

int ” is a primitive type.

A int variable stores a 32−bit integer value.


int number = 5;
int octalNumber = 0377;
int hexNumber = 0xff;

The int keyword can be used as a method parameter as below:

  1. public void displayAge(int age) {
  3.     System.out.println("Age of a person is "+age);
  4. }
public void displayAge(int age) {

    System.out.println("Age of a person is "+age);

The int keyword can be used as a return type of a method as well:

  1. public int getDisplayAge() {
  3.                 return 45;
  4. }
public int getDisplayAge() {
                return 45;

All integer literals in Java are 32−bit int values unless the value is followed by l or L as in 100L or 100l,
indicating that the value should be interpreted as a long.
