Write a function writel that will write the length of a side of a square. If only one argument is passed to the function, it is the length, and the output will go to the Command Window. If two arguments are passed, however, the first argument will be the length and the second argument will be the file identifier for an output file to which the length should be printed.

Acommon algorithm for converting a decimal number to binary is to repeatedly divide the decimal number by 2 and save the remainder. this division is continued until the result is zero. then, each of the remainders that have been saved are used to construct the binary number.write a recursive java method that implements this algorithm.it will accept a value of int and return a string with the appropriate binary character representation of the decimal number.my code: public class lab16{public string converttobinary(int input){int a; if(input > 0){a = input % 2; return (converttobinary(input / 2) + "" +a); } return ""; } }
