System.out.println("Decimal equivalent of "+ binary +" is "+ decimal);
}

private static int binaryToDecimal(String binary) {
final int base = 2;
int decimal = 0;
for (int i = 0; i < binary.length(); i++) {
if (binary.charAt(i) == ‘0’) {
decimal += 0 * Math.pow(base, binary.length() – i – 1);
} else if (binary.charAt(i) == ‘1’) {
decimal += 1 * Math.pow(base, binary.length() – i – 1);
} else {
