How to get a hex value from a decimal integer in Java?

I don't know how to generate a hex "0x83" character from an integer value in Java.

I need a "0x83" value to represent a letter in the Cyrillic alphabet (this letter: ѓ), in or开发者_如何学Cder to send it (the letter) to my printer. When converting 131 (0x83 in decimal) into hex with my converter (below) I get three numbers: 0x31, 0x33 and 0x31.

public String toHex(String arg) {
    return String.format("%x", new BigInteger(arg.getBytes()));
}

I need to get 0x83 from this conversion.

If you are trying to convert integer 131 to a hex string, you can try

Integer.toHexString( 131 )

It will return "83" as String.

Here's one example:

String str = Integer.toHexString(131);
System.out.println(str);

String cyrillic = Character.toString((char)0x83)

Have you tried checking out the Java Integer API. Here are a couple of examples:

I don't see a problem, when converting:

System.out.println(Integer.toHexString(131));

returns 83.

Two possibilities, either your printer needs 0x83 as a byte or as string/char

Send as a byte:

int Cyrillic_int = 131; 
byte Cyrillic = (byte) Cyrillic_int;

Or send a string representation of 0x83:

int Cyrillic_int = 131;
String Cyrillic = Integer.toHexString(131);
