Given a decimal number, Write a java program to convert decimal to binary number.
For example :
Input : 4 , Output : 100
Input : 5 , Output : 101
Input : 10 , Output : 1010

Java Program to Convert Decimal to Binary Number
In this coding example, we are going to write a java code which convert decimal number to binary number. Here is the list of things we have in this code.
i) In this program, we have store the remainder in an array, when the number is divided by 2.
ii) Then, In next step divide the number by 2.
iii) Repeat the above two steps until the number is greater than zero.
iv) In last step, print the array in reverse order.
