Java - convert long to binary String
13 points
In java simples way to convert long to binary String is to use Long.toBinaryString(number).
Simple example:
xxxxxxxxxx1
long number = 10_000_000_000L;2
String binaryString = Long.toBinaryString(number);3
4
System.out.println(binaryString); // 1001010100000010111110010000000000xxxxxxxxxx1
public class Example1 {2
3
public static void main(String[] args) {4
5
long number = 8;6
7
String binary = Long.toBinaryString(number);8
String numberPadding = String.format("%4s", number);9
10
System.out.println("long | binary");11
System.out.println(numberPadding + " - " + binary);12
}13
}Output:
xxxxxxxxxx1
long | binary2
8 - 1000xxxxxxxxxx1
public class Example2 {2
3
public static void main(String[] args) {4
5
long number = 31L * Integer.MAX_VALUE;6
7
String binary = Long.toBinaryString(number);8
9
System.out.println(" long | binary");10
System.out.println(number + " - " + binary);11
}12
}Output:
xxxxxxxxxx1
long | binary2

public static void main(String[] args) {4
5
System.out.println("long | binary");6
7
for (long number = 0L; number <= 8L; number++) {8
9
String binary = Long.toBinaryString(number);10
String numberPadding = String.format("%4s", number);11
12
System.out.println(numberPadding + " - " + binary);13
}14
}15
}Output:
xxxxxxxxxx1
long | binary2
