Answer:
Explanation:The program of the given question to display name and percentage of first ten toppers of the class is as follows:
import java.util.Scanner ; // created object called scanner
class School_Students // created class named School_Students
{
public static void main(String[] args)
{
String a[ ] = new String[35]; // variable string
int b[ ] = new int[35]; // variable integer
Scanner pin = new Scanner(System.in);
for (int i = 0; i < 35; i++) // loop
{
System.out.print("Enter the name of the student " + (i + 1) + " : "); // input from user is asked
a[i] = pin.nextLine();
System.out.print("Enter the percentage of the students : "); //input from user is asked
b[i] = pin.nextInt();
pin.nextLine();
}
int X=b.length;
for (int i=0; i<l-1; i++) // selection sort
{
int pop = i;
for (int j=i+1; j<l; j++)
{
if (b[j] > p[pop])
{
pop = j;
}
}
int X1 = b[pop];
b[pop] = b[i];
b[i] = X1; // percentage is swaped
String X2 = a[pop];
a[pop] = a[i];
a[i] = X2; // name is swaped
}
System.out.println("RANK \t NAME \t PERCENTAGE");
for (int i = 0; i < 10; i++)
{
System.out.println((i+1) + " \t " + a[i] + " \t " + b[i]); // top 10 students and their percentages are printed
}
}
}
