Binary-Decimal Algorithm The binary-to-decimal algorithm in Java involves processing each binary digit (bit) and calculating its decimal equivalent using positional values. Starting from the rightmost bit, multiply each bit by 2 raised to the power of its position and sum the results. For example, the binary number 101 is calculated as (1 * 2^2) + (0 * 2^1) + (1 * 2^0) = 5. This logic can be implemented manually or using Interparent(binaryString, 2) for efficiency. It's a key concept in number manipulation and number system conversions in Java.
