+## [WEEK 9](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/tree/WEEK-9)
+
+  [Java Week 9:Q1](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/blob/WEEK-9/Question91.java) Complete the code to develop a BASIC CALCULATOR that can perform operations like Addition, Subtraction, Multiplication and Division.
+```text
+Note the following points carefully:
+1. Use only double datatype to store calculated numeric values.
+2. Assume input to be of integer datatype.
+3. The output should be rounded using Math.round() method.
+4. Take care of the spaces during formatting output (e.g., single space each before and after =).
+5. The calculator should be able to perform required operations on a minimum of two operands as shown in the below example:
+
+Input:
+	       5+6 
+
+Output:
+	       5+6 = 11
+```  
+  [Java Week 9:Q2](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/blob/WEEK-9/Question92.java) Complete the code to develop an ADVANCED CALCULATOR that emulates all the functions of the GUI Calculator as shown in the image.

+
+```text
+Note the following points carefully:
+1. Use only double datatype to store all numeric values.
+2. Each button on the calculator should be operated by typing the characters from 'a' to 'p'.
+3. To calculate 25-6, User should input fjhkc (where, f for 2, j for 5, h for '-', k for 6 and c for '=' ).
+3. You may use the already defined function gui_map(char).
+4. Without '=', operations won't give output as shown in Input_2 and Output_2 example below.
+5. The calculator should be able to perform required operations on two operands as shown in the below example:
+
+Input_1:
+	       klgc
+
+Output_1:
+		18.0
+
+Input_2:
+	       klg
+
+Output_2:
+  ```
+
+  [Java Week 9:Q3](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/blob/WEEK-9/Question93.java) Complete the code to perform a 45 degree anti clock wise rotation with respect to the center of a 5 × 5 2D Array as shown below:
+```text
+INPUT:
+              00100
+              00100
+              11111
+              00100
+              00100
+
+OUTPUT:
+
+              10001
+              01010
+              00100
+              01010
+              10001
+
+Note the following points carefully:
+1. Here, instead of 0 and 1 any character may be given.
+2. The input and output array size must be of dimension 5 × 5 and nothing else.
+```
+
+  [Java Week 9:Q4](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/blob/WEEK-9/Question94.java) A program needs to be developed which can mirror reflect any 5 × 5 2D character array into its side-by-side reflection. Write suitable code to achieve this transformation as shown below:
+```text
+ INPUT:                                       OUTPUT:
+               OOXOO                                        OOXOO
+               OOXOO                                        OOXOO
+               XXXOO                                        OOXXX
+               OOOOO                                        OOOOO
+               XOABC                                        CBAOX
+
+Note the following points carefully:
+1. Here, instead of X and O any character may be present.
+2. The input and output array size must be of dimension 5 × 5 and nothing else.
+3. Only side-by-side reflection should be performed i.e. ABC || CBA.
+```
+
+  [Java Week 9:Q5](https://github.com/bkkothari2255/Programming_In_Java_NPTEL/blob/WEEK-9/Question95.java) Write suitable code to develop a 2D Flip-Flop Array with dimension 5 × 5, which replaces all input elements with values 0 by 1 and 1 by 0. An example is shown below:
+```text
+INPUT:
+               00001
+               00001
+               00001
+               00001
+               00001
+
+OUTPUT:
+
+               11110
+               11110
+               11110
+               11110
+               11110
+
+Note the following points carefully:
+1. Here, the input must contain only 0 and 1.
+2. The input and output array size must be of dimension 5 × 5.
+3. Flip-Flop: If 0 then 1 and vice-versa.
+```
