Java - convert int to binary String
6 points
In java simples way to convert integer to binary String is to use Integer.toBinaryString(number).
Simple example:
xxxxxxxxxx1
int number = 8;2
String binaryString = Integer.toBinaryString(number);3
4
System.out.println(binaryString); // 1000Convert int to binary String with leading zeros:
xxxxxxxxxx1
int number = 8;2
3
String binaryString = Integer.toBinaryString(number);4
String withLeadingZeros = String.format("%8s", binaryString).replace(' ', '0');5
6
System.out.println(binaryString); // 10007
System.out.println(withLeadingZeros); // 00001000More on this topic under link:
Java - convert int to binary String with leading zeros
xxxxxxxxxx1
public class Example1 {2
3
public static void main(String[] args) {4
5
System.out.println("int | binary");6
7
int number = 8;8
9
String binary = Integer.toBinaryString(number);10
String intPadding = String.format("%3s", number);11
12
System.out.println(intPadding + " - " + binary);13
}14
}Output:
xxxxxxxxxx1
int | binary2
8 - 1000xxxxxxxxxx1
public class Example2 {2
3
public static void main(String[] args) {4
5
System.out.println("int | binary");6
7
for (int number = 0; number <= 8; number++) {8
9
String binary = Integer.toBinaryString(number);10
String intPadding = String.format("%3s", number);11
12
System.out.println(intPadding + " - " + binary);13
}14
}15
}Output:
xxxxxxxxxx1
int | binary2
0 - 03
1 - 14
2 - 105
3 - 116
4 - 1007
5 - 1018
6 - 1109
7 - 11110
8 - 1000
