# Java program using bitwise operations

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

Implement your solution using one class. In your class, provide two methods - main and display.

main method:

· Declare int number = 128;
· Include a while loop that loops while number is >= -128.
· Call the display method, which prints the value of its passed-in number parameter.
· If number is greater than zero, use the >>= operator to do one arithmetic-right shift.
· If number equals zero, use the ~ operator to complement it.
· If number is less than zero, use the <<= operator to do one left shift.
· After the while loop, ask the user to input any number, and call the display method to print that number.

display(number) method:

Write the display(number) method like this:

· Print number's value and a tab. (t is tab in java)
· Assign to a local variable named mask the value 1 shifted left 31 times. This puts a 1 in bit 31 and zeros in all other bits.
· Use a for loop to step through all 32 bits, doing the following in each step:
o Use a conditional operator whose condition is (mask & number != 0) to print either 1 or 0.
o After every fourth bit, print a single space to make the output readable.

-4 1111 1111 1111 1111 1111 1111 1111 1100
-8 1111 1111 1111 1111 1111 1111 1111 1000
-16 1111 1111 1111 1111 1111 1111 1111 0000
-32 1111 1111 1111 1111 1111 1111 1110 0000
-64 1111 1111 1111 1111 1111 1111 1100 0000
-128 1111 1111 1111 1111 1111 1111 1000 0000

Enter any integer: 127

127 0000 0000 0000 0000 0000 0000 0111 1111

Attached is what I have come up with but am making a mistake somewhere because I can't get it to compile and run.
