scanner java api code example

Example 1: java scanner

import java.util.Scanner;

// import scanner 

Scanner myScanner = new Scanner(System.in); // Make scanner obj

String inputString = myScanner.nextLine(); // Take whole line

boolean inputBoolean = myScanner.nextBoolean(); //Boolean input

long inputLong = myScanner.nextLong(); //Interger,long ... input

Example 2: scanner in java

import java.util.Scanner;		//Import Scanner in java

class classname{
  public void methodname(){
    Scanner s_name = new Scanner(System.in);	//Scanner declaration
    //Use Scanner object to take input
    int val1    =  s_name.nextInt();			//int
    float val2  =  s_name.nextFloat();			//float
    double val3 =  s_name.nextDouble();			//double
    string name =  s_name.nextLine();			//string
    char ch     =  s_name.nextLine().charAt(0);	//character
  }}

Example 3: java scanner

import java.util.Scanner;//import Scanner

Scanner input=new Scanner(System.in);//Create the scanner Obj

float numF = input.nextFloat();//Returns float
int num1 = input.nextInt(); //Returns int
byte byte1 = input.nextByte();//Returns Byte
long lg1 = input.nextLong();//Returns long
boolean b1 = input.nextBoolean();//Returns bool
double num2 = input.nextDouble();//Returns Double
String nome = input.nextLine();//Returns String

//execution is pause until you give input

Example 4: how to use scanner class in java

// import Scanner
import java.util.Scanner;

// Initialize Scanner
Scanner input = new Scanner(System.in);

// Test program with Scanner
System.out.println("What is your name?");
String name = input.nextLine();

System.out.println("Hello," + name + " , it is nice to meet you!");

Example 5: scanner java

Scanner sc = new Scanner(System.in);
     int i = sc.nextInt();
