int keyword in java
” int ” is a primitive type.
A int variable stores a 32−bit integer value.
Examples
int number = 5;
int octalNumber = 0377;
int hexNumber = 0xff;
The int keyword can be used as a method parameter as below:
- public void displayAge(int age) {
- System.out.println("Age of a person is "+age);
- }
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:
- public int getDisplayAge() {
- return 45;
- }
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.
