Using JAVA We ask to write a static method called conversionBinaryDecimal which takes as argument a one-dimensional array containing only 0s and 1s and returns a decimal integer x, decimal equivalent of the elements of the array placed one next to the other: For example running the following code

public static void main(String[] args) { int[] a = {1,0,0,1}; System.out.println("a="+conversionBinaireDecimale(a)); int[] b = {1,0,1,0}; System.out.println("b="+conversionBinaireDecimale(b)); int[] c = {1,0,1,0,1,1}; System.out.println("c="+conversionBinaireDecimale(c)); int[] d = {1,0}; System.out.println("d="+conversionBinaireDecimale(d)); }

output

a=9 b=10 c=43 d=2
