Java two's complement binary to integer
binary, java, twos-complement
Solution
You need to read the result into `short`.
short res = (short)Integer.parseInt("1111111111001110", 2);
System.out.println(res);
This prints `-50`.
Problem
I know that converting a decimal to binary with `Integer.toBinaryString(355) = 0000000101100011` and `Integer.toBinaryString(-355) = 1111111010011101` (where I take the lower 16 bits of the 32 bit result). What I would like to do is the other way and take a 16-bit twos's complement binary string and to convert to decimal. i.e. ``` 0000000000110010 = 50 1111111111001110 = -50 ``` Rather than `1111111111001110 = 65486` How would I do this?
