If we want to take input from user in JAva language then we have two option .
1. import Scanner Class. 2. Bufferreader
Step1. 1st of all we import scanner class.
import java.util.Scanner;
Steps 2. After that we create object of Scanner Class.
Scanner objsc=new Scanner(System.in);
Step 3. After creating object we are eligible for taking input from user.
int a=objsc.nextInt();
float b=objsc.nextFloat();
String name=objsc.next();
