How I can write a code getting the age of the user then if the age is > 18 print welcome else print too young ?

Question

I am a beginner learning java and I need to practice on how to use Scanner , variable and if statement .

I know how to code all of them but Idk how to connect the data I get from the user by "Scanner" with if statement or with the variable then if statement

Answer 1

Simpley store you data taken by user in veriable and check if user is young or not
Ex storing value in veriable
Scanner obj = new Scanner(System.in);
int age = obj.nextInt();

Answer 3

For Scanner : import class Scanner by
import java.util.Scanner ;
Make Scanner object by
Scanner in=new Scanner(System.in);
Now you have varying methods for taking input for specific inputs..
if(condition)
{
...
}
Ex:
int age=18;
if(age>18)
System.out.println("Adult");
else
System.out.println("young") ;

For all these you can find better explanation from tutorial link:

Answer 5

Scanner in=new Scanner(System.in);
//To Store an int
int age=in.nextInt();

//Store a long
long age=in.nextLong();

//Store a float
float =in.nextFloat();

//Store a double
double age=in.nextDouble();

//Store a boolean -
boolean b=in.nextBoolean();

//Store a complete line -
String s=in.nextLine();

//Read a word -
String word=in.next();

//Store a byte -
byte a=in.nextByte();

Or if(in.nextInt() > 18) {....}
