- Write the following programs in Java: In the Converter class write the static method, bin2decimal(String bin). The parameter for this method is an unsigned (nonnegative) binary number represented by a string. The method returns the decimal equivalent for the binary parameter, as an integer.If the binary string is invalid (contains characters other than ‘0’ and ‘1’), the method returns -1. Convert from a binary (b) string with up to 16 digits to decimal (d) using the following formula:? = ?0 + ?1 × 2 + ?2 × 22 +⋯+ ?7 × 215where b0, b1, ?2, … ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 + 0×2 + 1×22 + 1×23 = 13 in decimal. Side note: You may NOT use the decode method of the Long wrapper class instead of this formula. In the Converter class write another static method, english2encrypted(String english). The parameter for this method is a word or sentence represented by a string. The word or sentence should only contain letters (no digits,…THIS NEEDS TO BE DONE IN C#! NOT JAVA! NOT C++, NOT PYTHON! PLEASE WRITE THIS IN C#!
