    Default please help java noob here

    hey guys new to the forum and java. I am taking a java class and can seem to figure out how to fix this error below is my code any help is appreciated. i have to imput a binary number and have the decimal, ascii and result of decimal subtracted from 256 on 3 separate lines

    import java.util.Scanner;
    import java.lang.Integer;
    public class Binary {
    public static void main(String[] args) {
     
    Scanner in = new Scanner (System.in);
     
    // enter binary
    int b = in.nextint();
     
    // convert to decimal
    int decimalValue = Integer.parseInt(b, 2);
     
    // output decimal
    System.out.println(decimalValue);
     
    // add ascii output
     
    //add subtraction output
     
    	}
    }

    i keep getting the following when i try to compile

    Binary.java:8: cannot find symbol
    symbol : method nextmethod()
    location: class java.util.Scanner
    int b = in.nextmethod();
    ^
    Binary.java:10: cannot find symbol
    symbol : method parseInt(double,int)
    location: class java.lang.Integer
    int decimalValue = Integer.parseInt(b, 2);
    ^

    cannot find symbol
    symbol : method nextmethod()
    The compiler can not find a definition for that method. Read the API doc for the class and find the correct name for the method that will do what you want.

    cannot find symbol
    symbol : method parseInt(double,int)
    The compiler can not find a parseInt() method that takes a double and int for its args. Read the API doc for that method and see what types of args it takes.

    The API doc link: Java Platform SE 7


    BTW The error messages did NOT come from the posted code. You need to post the code and its error messages. Don't post code for a different version of the program than the one where the error messages came from.
    If you don't understand my answer, don't ignore it, ask a question.
