java: not statement 2 answers

i using next code convert 0 , 1's string binary , write file.

i getting error @ line 4:

code.java:56: error: not statement nextbyte << 1;

code:

public void writetofile(string binarystring, outputstream os){ int pos = 0; while(pos < binarystring.length()){ byte nextbyte = 0x00; for(int i=0;i<8 && pos+i < binarystring.length(); i++){ nextbyte << 1; nextbyte += binarystring.charat(pos+i)=='0'?0x0:0x1; } os.write(nextbyte); pos+=8; } }

you should assign result of operator variable :

nextbyte = nextbyte << 1;
