Strike through line meaning

Question

Jdev 11g release2, ADF BC.
hi, I am coding some program, but got some strike through lines on some words. eg. my code like: ValueBinding vb = fc.getApplication().createValueBinding(expr)
then the strike through lines on "ValueBinding" and "createValueBinding". May you let me know what's the meaning it is? Thanks!

Actually I followed the sample from smuenchadf's example #85. the whole program as following:

but somehow the " ((bytesRead = in.read(buffer, 0, 8192))" is red underlined. i have no idea whether it is correct or wrong. i am using Jdev 11g r2.
