How do you convert a number from one base to another base in Java?
Safarov answered
First you should keep in mind that Java only stores decimal system, for other systems you will need String type to store in memory. Here are some declarations of numbers in different systems:
Integer base10 = 100; // decimal number
String base2 = "1110" // binary number
String base16 = "FF" // hexadecimal number
To convert any base to decimal you will need following code:
Integer.parseInt("1110", 2); // converts any String ( here "1110" ) from binary to decimal and returns Integer (here 14)
To convert decimal to any base you will need toString() method:
Integer.toString(256, 16); // converts any Integer (here 100) from decimal to hexadecimal and returns String ( here "FF" )
