Question

I am trying to convert a number to hexadecimal. How do I do this without using modulus, division, and multiplication. Also, I can't import anything and I can't use any functions like Integer.toHexadecimal().

Step 1

To convert a decimal number into hexadecimal form with out using any of modulus, division or multiplication operator you need to use shift operators.

Step 2

The following code can be used to convert the number in decimal form into hexadecimal form using right shift operator:

Step 3

In the above program the for loop in line 39 will execute 7 times for the int type storage of 4 bytes. During the first iteration i will take the value of 7 i.e. (2×4) –1 =7. Then in the line 40, the input number “num” will be right sh...
