Here the input for string is " hi how are you" but I am getting output as "hi" alone. Do let me know where is the error. I have tried out with nextLine() also.
import java.util.Scanner;
public class Stringintalter {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc=new Scanner(System.in);
System.out.println("enter the num");
int a = sc.nextInt();
System.out.println("Enter the Double");
double b = sc.nextDouble();
System.out.println("Enter the string");
String c = sc.next(); //tried out with nextLine() also.
System.out.println(c);
System.out.println(b);
System.out.println(a);
}
}
This is basic error only. I browsed a lot still I am not able to sort out the error.
everytime you do
int a = sc.nextInt();
double b = sc.nextDouble();
your scanner is not reading the newLine token, so you should do something like:
System.out.println("enter the num");
int a = sc.nextInt();
sc.next();
System.out.println("Enter the Double");
double b = sc.nextDouble();
sc.next();
System.out.println("Enter the string");
String c = sc.next(); //tried out with nextLine() also.
This code worked out for me.
import java.util.Scanner;
public class Stringintalter {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("enter the num");
int a = sc.nextInt();
System.out.println("Enter the Double");
double b = sc.nextDouble();
System.out.println("Enter the string");
sc.nextLine();
String c = sc.nextLine();
System.out.println(c);
System.out.println(b);
System.out.println(a);
}
}
Maybe this code will help you.
Scanner u = new Scanner(System.in);
Scanner sc=new Scanner(System.in);
System.out.println("enter the num");
int a = sc.nextInt();
System.out.println("Enter the Double");
double b = sc.nextDouble();
System.out.println(b);
System.out.println(a);
String c;
c = u.nextLine();
System.out.println(c);
