The following code has incorrect extra underscores (_) after the 0b and 0x notations:

int decimalNotation = 2_000_000; // 2 million
int binaryNotation = 0b_0001_1110_1000_0100_1000_0000; // 2 million
int hexadecimalNotation = 0x_001E_8480; // 2 million

The code should be:

int decimalNotation = 2_000_000; // 2 million
int binaryNotation = 0b0001_1110_1000_0100_1000_0000; // 2 million
int hexadecimalNotation = 0x001E_8480; // 2 million
