字符串到int的转换错误

Question

My string contains floating numbers with positive and negative sign and character. Basically complex numbers. I have to separate them first from string then further as real and imaginary, keeping in mind that sign should remain along the number.

Currently, I am using Split to get them separated as sub strings but further in separating real and imaginary I get error reading negative sign. Need help.

this is my string "-0.6026630828112783-0.6026630828112783 i+0.012343244232-0.90293888321i..."

I use String.split("[\\Q+-\\Ei]"); and i get -0.6026630828112783-0.6026630828112783i (1st number). i further want to separate real and imaginary along with sign

Use Below Code to Convert String to int :)

Integer.parseInt("" +  Math.round(Float.parseFloat("-12.233")))

For Split numbers, First Add Separator Char before + and - . Like , . Then Split by Separator Char.
