    I want to enter value of a,b and c by the user (I can not do that using Log window in JDeveloper 12 c)  in the following program?

    import java.util.Scanner;

    public class Class2 {
        public static void main(String[] args) {
            int a,b,c;
                           Scanner s=new Scanner(System.in);
                            System.out.println("Enter the value a");
                            a=s.nextInt();

            System.out.println("Enter the value b");
                            b=s.nextInt();
            System.out.println("Enter the value c");
                            c=s.nextInt();
                            int k=(b*b)-4*a*c;
                            if(k<0)
                            {
                                    System.out.println("No real roots");
                            }
                            else
                            {
                                    double l=Math.sqrt(k);
                                    x=(-b-l)/2*a;
                                    y=(-b+l)/2*a;
                                    System.out.println("Roots of given equation:"+x+" "+y);
                            }
                   


        }
    }

    I cant not enter value after run the java program?

    Please move your thread to the JDeveloper forum if you question is about that product.

    If your question is about how to use JScanner then please read and follow the trail in The Java Tutorials

    https://docs.oracle.com/javase/tutorial/essential/io/scanning.html

    Scanning

    Objects of type Scanner are useful for breaking down formatted input into tokens and translating individual tokens according to their data type.

    That doc has WORKING example code.
