Binary, octal, and hexadecimal Conversions in Java

Convert from Binary, octal or Hex to Decimal using Integer.parseint (String input, int radix)

Use-to Integer.parseInt(String input, int radix) -convert from any type of Integer .

String binarynumber = "10101"; int decimal1 = Integer.parseint (Binarynumber, 2); System.out.println (Binarynumber + "in Base:" + decimal1); String Octalnumber = "456"; int decimal2 = Integer.parseint (Octalnumber, 8); System.out.println (Octalnumber + "in Base:" + decimal2); String hexnumber = "ABCD"; int decimal3 = Integer.parseint (Hexnumber, 16); System.out.println (Hexnumber + "in base:" + Decimal3), output:10101 in base 10:21456 in base 10:302ABCD in base 1 0:43,981

Convert from Decimal to Binary, octal or Hex using integer.tostring (int input, int radix)

Use-to-convert from a to any Integer.toString(int input, int radix) Integer type of base number.

Integer decimal1 = 21; String Binarynumber = integer.tostring (Decimal1, 2); System.out.println (Decimal1 + "in Base 2:" + binarynumber); Integer decimal2 = 302; String Octalnumber = integer.tostring (Decimal2, 8); System.out.println (Decimal2 + "in Base 8:" + octalnumber); Integer decimal3 = 43981; String Hexnumber = integer.tostring (Decimal3, 16);  System.out.println (Decimal2 + "in base:" + Hexnumber), output:21 in base 2:10101302 in base 8:45643981 in base 16 : ABCD

Convert from Decimal to Binary, octal or Hex using integer.toxxxstring (int)

IntegerClass does provide lots of unitily methods to be consumed directly. Check out the them in Java Doc.

Integer decimal1 = 21; System.out.println (Decimal1 + "in Base 2:" + integer.tobinarystring (decimal1)); Integer Decimal2 = 302; System.out.println (Decimal2 + "in Base 8:" + integer.tooctalstring (decimal2)); Integer decimal3 = 43981;  System.out.println (Decimal3 + "in base:" + integer.tohexstring (DECIMAL3)), output:21 in base 2:10101302 in base 8: 45643981 in Base 16:ABCD
