import java.util.stream.IntStream;
public class Convert_Decimal_Number_To_Binary_Java8_Example {
public static void main(String[] args) {
int decimalNumber = 100;
String binaryValue = IntStream.iterate(decimalNumber, a -> a / 2)
.limit(32)
.map(b -> b % 2)
.mapToObj(String::valueOf)
.reduce("", (x, y) -> y + x);
System.out.println("The Binary value of " + decimalNumber + " is: " + binaryValue);
}
}
Output:
The Binary value of 100 is: 00000000000000000000000001100100

In the above example, It uses IntStream and using it’s iterate method to repeatedly divide the decimal number by number 2, until the result of the division becomes 0. Then, the limit method is used to limit the number of iterations to 32, which is basically the number of bits in an int. After that, map method is used to get the remainder of each division, which is basically the binary digit at that place. After applying map method, now it comes to apply the mapToObj method to convert each binary digit to a string, and finally, it’s the reduce method which is used to concatenate all the binary digits into a single string. And, Then using sysout method, we are printing the resulting binary string to the console.
