 A departmental shop has 5 stores and 6 departments. The monthly sale of the department is kept in the Double Dimensional Array (DDA) as m[5][6]. The manager of the shop wants to know the total monthly sale of each store and each department at any time. Write a program to perform the given task. Hint: Number of stores as rows and Number of departments as columns. import java.util.Scanner; class Department{ public static void main(String args[]){ Scanner sc=new Scanner(System.in); int deptshop[][] = new int[5][6]; //5 stores(rows) 6 deparments(columns) int sales[] = new int[5]; //total sales data for 5 stores for(int i=0;i<5;i++){ //row System.out.println("Enter data for store:"+(i+1)); int sum=0; for(int j=0;j<6;j++){ //column System.out.println("Enter sales amount into department "+(j+1)); deptshop[i][j]=sc.nextInt(); sum=sum+deptshop[i][j]; } sales[i]=sum; //store the total sales amount for each store } ...

/** Suppose : VAT ASCII code of V : 86 -64 => 22 ASCII code of A : 65 - 64 => 1 ASCII code of T : 84 - 64 => 20 Position of V: 22 Position of A: 1 Position of T: 20 Subtract the ascii value with 64,so we get the position values To join the position values together, VAT => 22120 We need to perform this calculate 2*2+2*2+1*1+2*2+0*0 => 13 1*1+3*3 => 10 1*1+0*0 => 1 If we get 1 at the very end, then this is Happy Word */ import java.util.Scanner; class HappyWord {  public static void main(String args[])  {   Scanner sc = new Scanner(System.in);   System.out.println("Enter a word: ");   String str = sc.next().toUpperCase();   String num="";   for(int i=0;i<str.length();i++)   {    char ch = str.charAt(i); //we get each every character    int ascii = (int)ch;    int pos=ascii-64;    num=num+Integer.toString(pos);   }   System.out.println("The combined position is "+num);   i...
