Calculate and print the average (this works) Search for Joel in the list, print his data----for some reason this is outputting the wrong data and is outputting an infinite loop. Why? import java.util.*; import java.text.DecimalFormat; public class parallel { public static void main (String[]args) { Scanner input=new Scanner (System.in); DecimalFormat fmt=new DecimalFormat ("0.##"); double[]gpa=new double [5]; String[]name=new String [5]; int[]id=new int [5]; double avg=0.0; double sum=0.0;

    for (int i=0;i<gpa.length;i++)
    {
        System.out.println("Enter a name: ");
        name[i]=input.nextLine();
        System.out.println("Enter GPA: ");
        gpa[i]=input.nextDouble();
        System.out.println("Enter ID: ");
        id[i]=input.nextInt();
        input.nextLine();
    }

    for (int i=0;i<name.length;i++)
    {

        System.out.println("Name: "+name[i]+ " id: "+id[i]+ " gpa: "+gpa[i]);        
    }
    for (int i=0;i<gpa.length;i++)
    {
    sum=sum+gpa[i];    
    }
    avg=sum/gpa.length;
    System.out.println(fmt.format(avg));

    System.out.println("Enter a name to search: ");
    String enter=input.nextLine();
    int i=0;
    boolean found=false;
    do{
        if (name[i].equals(enter))
            found=true;

            System.out.println(id[i]);
            System.out.println(gpa[i]);
        }while (i<enter.length()&&!found);

}

}
