Do not add the elements of a vector

I have a problem when adding elements of a vector (do not add them and print each element instead of printing the total sum of the elements) and I do not know what is wrong, I hope you can help me!

What I want is for you to add all the elements you have entered and print them.

Example:

Ingrese la cantidad de elementos: 3
Ingrese valor: 2
Ingrese valor: 2
Ingrese valor: 2

La suma es: 6

package _Vector_Tamaño;
import java.util.Scanner;

/*
Desarrollar un programa que permita ingresar un vector de n elementos, ingresar n por teclado.
Luego imprimir la suma de todos sus elementos
*/

public class Problema1 {
private Scanner teclado;
private int[] elementos;
private int suma;

public void cargar() {
    teclado = new Scanner(System.in);
    int n;
    System.out.print("Ingrese la cantidad de elementos: ");
    n = teclado.nextInt();
    elementos = new int[n];

    for(int f = 0; f < elementos.length; f++) {
        System.out.print("Ingrese valor: ");
        elementos[f] = teclado.nextInt();
    }
}

public void suma() {
    suma = 0;

    for(int f = 0; f < elementos.length; f++) {
        suma = suma + elementos[f];
    }

}

public void imprimir() {
    System.out.println("La suma es: " + suma);
}

public static void man(String[] ar) {
    Problema1 prob = new Problema1();
    prob.cargar();
    prob.suma();
    prob.imprimir();
}

}
