This article shows you five examples to convert a string into a binary string representative or vice verse. Convert String to Binary – Integer.toBinaryString Convert String to Binary – Bit Masking Convert Binary to String – Integer.parseInt Convert Unicode String to Binary. Convert Binary to Unicode String. 1. Convert String to Binary – Integer.toBinaryString The […]
In Java, we can use Integer.toBinaryString(int) to convert an Integer to a binary string representative. Integer.java public final class Integer extends Number implements Comparable<Integer>, Constable, ConstantDesc { public static String toBinaryString(int i) { return toUnsignedString0(i, 1); } //… } This article will show you two methods to convert an Integer to a binary string representative. […]
In Java, we can use Integer.toBinaryString(int) to convert a byte to a binary string representative. Review the Integer.toBinaryString(int) method signature, it takes an integer as argument and returns a String. Integer.java public final class Integer extends Number implements Comparable<Integer>, Constable, ConstantDesc { public static String toBinaryString(int i) { return toUnsignedString0(i, 1); } //… } If […]
Review the following Java example to convert a negative integer in binary string back to an integer type. String binary = Integer.toBinaryString(-1); // convert -1 to binary // 11111111 11111111 11111111 11111111 (two’s complement) int number = Integer.parseInt(binary, 2); // convert negative binary back to integer System.out.println(number); // output ?? The result is NumberFormatException! Exception […]
In Python, we can use bin() or format() to convert an integer into a binary string representation. print(bin(1)) # 0b1 print(bin(-1)) # -0b1 print(bin(10)) # 0b1010 print(bin(-10)) # -0b1010 print("{0:b}".format(10)) # 1010 print("{0:#b}".format(10)) # 0b1010 , with 0b prefix print("{0:b}".format(10).zfill(8)) # 00001010 , pad zero, show 8 bits print(format(10, "b")) # 1010 print(format(10, "#b")) # […]
This article shows you how to format a string in Java, via String.format(). Here is the summary. Conversion Category Description %b, %B general true of false %h, %H general hash code value of the object %s, %S general string %c, %C character unicode character %d integral decimal integer %o integral octal integer, base 8 %x, […]
In Java, byte is an 8-bit signed (positive and negative) data type, values from -128 (-2^7) to 127 (2^7-1). For unsigned byte, the allowed values are from 0 to 255. Java doesn’t have unsigned bytes (0 to 255). To make an unsigned byte, we can cast the byte into an int and mask (bitwise and) […]
The BITAND function treats its inputs and its output as vectors of bits, the output is the bitwise AND of the inputs. Basically it performs below steps. Converts the inputs into binary. Performs a standard bitwise AND operation on these two strings. Converts the binary result back into decimal and returns the value. 1. BITAND […]
