Write a program to input and sort the weight of ten people. Sort and display them in descending order using the selection sort technique.
Answer
import java.util.Scanner;
public class KboatSelectionSort
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
double weightArr[] = new double[10];
System.out.println("Enter weights of 10 people: ");
for (int i = 0; i < 10; i++) {
weightArr[i] = in.nextDouble();
}
for (int i = 0; i < 9; i++) {
int idx = i;
for (int j = i + 1; j < 10; j++) {
if (weightArr[j] > weightArr[idx])
idx = j;
}
double t = weightArr[i];
weightArr[i] = weightArr[idx];
weightArr[idx] = t;
}
System.out.println("Sorted Weights Array:");
for (int i = 0; i < 10; i++) {
System.out.print(weightArr[i] + " ");
}
}
}Output

Define a class to accept values into 4x4 array and find and display the sum of each row.
Example:
A[][]={{1,2,3,4},{5,6,7,8},{1,3,5,7},{2,5,3,1}}
