            sum=sum+a[l];
            System.out.println("Sum: "+sum);
}

public static void input(int[] b){
        Scanner uk=new Scanner(System.in);
        System.out.println("Enter 5 numbers");
        for(int l=0;l<b.length;l++){
        b[l]= uk.nextInt();
    }
}

public static void main(String[] args) {
    int z[]=new int[5];
    PassArrayToTheMethod.input(z);
