12. bit manipulation using int in java stackoverflow.comI have an int and I want to invert the bits of it using the ~ bit operator. This should be a very simply thing to do, however I tried and ... 
13. unsigned 8 bit integers,, and checksums coderanch.com1) how would I represent unsigned 8 bit integers in Java? Can I do this using a type or should I use byte, write out the value in unsigned 8 bit binary, and then reverse out the 2's complement to get the value? As an example 16 decimal = 0001 0000 and that works fine as it's not a 2's complement ... 
14. integer bit values coderanch.comI'm having some trouble with some pretty basic stuff, and I was hoping someone could give me a hand. I need to write a program that asks the user to enter an integer and bit position. The program then needs to write out the value of the bit in that position of the integer (1 or 0). I know this sounds ...

17. Generate bits out of int? coderanch.comThanks for reply. Following is my algorithm (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11 Yes, it is basics and I believe I learnt in 5th grade . I know on a piece of paper, I can calculate. 1 0 1 1 But in ... 
18. Integer.toBinaryString()  4 bits every time forums.oracle.comI am using the Integer.toBinaryString() method to convert ints between 1 and 14 into binary.I would like them to be 4 bits long every time, i.e 2 = 0010. At the moment a 2 would be represented as 10. I need them as 4 bits because i will be concatenating 6 of these binary strings together, and losing length will completely ... 
19. Reproduce Integer from Bits forums.oracle.comWhat's the format of the bits? If it's binary bits (not encoded) then put the bits in a string and use Integer.parseInt. If the bits are encoded, then you'll need to interpret the bits  Java can interpret IEE754 formats using Double.longBitsToDouble. I don't believe any other encodings are provided by standard Java. 
20. Float.intBitsToFloat(int bits) question about endianess forums.oracle.comterps128 wrote: I am confused about how Float.intBitsToFloat() works. If I give it say 123, will it look at 1 as the most significant digit or 3? The most significant digit is always the one that has the highest influence on the value. In the (decimal) number 123 the most significant digit is 1, because changing it to anything else changes ... 
21. 128bit int and 128bit double. forums.oracle.comjschell wrote: Just a suggestion but you might find it reasonable for that problem domain to do it yourself. Certainly a lot of work but possible. You would probably see it sooner than with the RFE. Probably help the RFE along to see how feasible it is. Imagine 128bit long to be easier to implement first. Actually this would be the ... 
22. bit manipulation  converting int value to 4 bits forums.oracle.comIs there someway of converting int values to a set number of bits without affecting the other bits in the byte. If I have a byte and I the first 3 bits are reserved and the other 5 bits represent a number. So I need convert a number to the 5 bits without changing the values in the first 3 bits. ...
