Queries and Questions

i want to get the integer i.e decimal number corresponding to the binary string nc. However this does not happen despite using parseInt(). for eg if nc=”11000101″ then edcode is also having the same value instead of giving me the decimal representation of nc. Can anyone please help

String codest="11010101";char[] codear=codest.toCharArray();
codear[4]=codear[5];String nc=newString(codear);int edcode=Integer.parseInt(nc);

int edcode=Integer.parseInt(nc, 2); This will work

thank you 🙂 i would be grateful if you explain the logic behind it –  Manika Mar 19 at 9:46
JRE needs to know about the base of your number. –  Varun Mar 19 at 10:12
JRE needs to know about the base of your number. If number is in binary, we need to tell JRE that number is in binary format. For the same reason we passed 2 as binary is base 2. I hope this explains well. Please refer this for more details.docs.oracle.com/javase/7/docs/api/java/lang/…, int) –  Varun Mar 19 at 10:18
