Question

I have a Java Programming question. I have the following code and at Scanner.nextLine(); it is telling me that I "Cannot make a static reference to the nonstatic method nextLine() from the type Scanner" I can't figure out how to correct this.

import java.io.PrintStream;

import java.util.Scanner;

public class QuartsToGallonsWithExceptionHandling {

QuartsToGallonsWithExceptionHandling(){

}

public static void main(String args[]){

int i = 18;

boolean flag = false;

Scanner scanner = new Scanner(System.in);

while(!flag)

try{

System.out.println("enter quarts needed >> ");;

i = scanner.nextInt();

flag = true;

}

catch(Exception exception){

Scanner.nextLine();

System.out.println("Invalid data entry");

}

int j = i / 4;

int k = i / 4;

System.out.println((new StringBuilder()).append("A job that needs ")

.append(i).append(" quarts requires ")

.append(j).append(" gallons plus ")

.append(k).append(" quarts.").toString());

}

}

Explanation / Answer

Correct This : scanner.nextLine();

After CatchException

In Coding Find Scanner.nextLine(); and used scanner in small Letter

import java.io.PrintStream;

import java.util.Scanner;

public class QuartsToGallonsWithExceptionHandling {

QuartsToGallonsWithExceptionHandling(){

}

public static void main(String args[]){

int i = 18;

boolean flag = false;

Scanner scanner = new Scanner(System.in);

while(!flag)

try{

System.out.println("enter quarts needed >> ");;

i = scanner.nextInt();

flag = true;

}

catch(Exception exception){

scanner.nextLine();

System.out.println("Invalid data entry");

}

int j = i / 4;

int k = i / 4;

System.out.println((new StringBuilder()).append("A job that needs ")

.append(i).append(" quarts requires ")

.append(j).append(" gallons plus ")

.append(k).append(" quarts.").toString());

}

}
