Java, finish the recursive function that converts a binary string to decimal, do not change main or function header.

public static void main( String[] args ) {
if( binToDec( "1101100" ) == 108 ) {
System.out.println( "binToDec1 is correct!" );
}
if( binToDec( "1011101" ) == 93 ) {
System.out.println( "binToDec2 is correct!" );
}

}

public static int binToDec( String bin ) {

Answer:

public class BinaryToDecimalRecursive {

    public static void main(String[] args) {
        if (binToDec("1101100") == 108) {
            System.out.println("binToDec1 is correct!");
        }
        if (binToDec("1011101") == 93) {
            System.out.println("binToDec2 is correct!");
        }

    }

    public static int binToDec(String bin) {
        if (bin.isEmpty()) {
            return 0;
        } else {
            return binToDec(bin.substring(0, bin.length() - 1)) * 2 + (bin.charAt(bin.length() - 1) - '0');
        }
    }
}

binToDecl is correct! binToDec2 is correct! Process finished with exit code 0

    in java Part 1 In this section, we relook at the main method by examining passing array as parameters. Often we include options/flags when running programs. On command line, for example, we may do “java MyProgram -a -v". Depending on options, the program may do things differently. For example, "a" may do all things while "-v" display messages verbosely. You can provide options in Eclipse instead of command line: "Run ... Run Configurations ... Arguments". Create a Java class (Main.java)....
