Write a program in JAVA to read in a 32-bit pattern and translate to a IEEE-754 floating point number. Do not use library routines. Be sure to look for infinity, -infinity, zero and NaN patterns. ( This is what I NEED, My SPECIFIED NEED is please use the import: import javax.swing.JOptionPane; for the input and output, then a loop to check and see if there are any special patterns, example: NaN, -infinity, infinity, ect... If not check it with something like this ..............

sign=(inputString.CharAt(0)=='0'?1:-1);

String expString=inputString,substring(1,8);

String mainString=inputSting.substring(9)

Relatively new to coding, so the simpler the better. That way I understand what I am doing , thanks
