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);

}
```
