# Java Program to Convert Decimal to Hexadecimal

This post covers a program in Java that converts a decimal number entered by user at run-time of the program, to its equivalent hexadecimal value.

If you're not aware about, how the decimal to hexadecimal conversion takes place, then refer to Decimal to Hexadecimal Conversion.

## Decimal to Hexadecimal Conversion in Java

The question is, write a Java program to convert decimal to hexadecimal. The decimal number must be received by user at run-time. The program given below is its answer:

```import java.util.Scanner;

public class CodesCracker
{
public static void main(String[] args)
{
int decimal, rem, i=0;

Scanner scan = new Scanner(System.in);

System.out.print("Enter the Decimal Number: ");
decimal = scan.nextInt();

while(decimal!=0)
{
rem = decimal%16;
if(rem<10)
rem = rem+48;
else
rem = rem+55;
i++;
decimal = decimal/16;
}

for(i=(i-1); i>=0; i--)
}
}```

The snapshot given below shows the sample run of above program, with user input 540 as decimal number to convert and print its equivalent hexadecimal value:

The above program can also be created in this way:

```import java.util.Scanner;

public class CodesCracker
{
public static void main(String[] args)
{
int decimal, rem;
char[] hexDigit = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};

Scanner scan = new Scanner(System.in);

System.out.print("Enter the Decimal Number: ");
decimal = scan.nextInt();

while(decimal>0)
{
rem = decimal%16;
decimal = decimal/16;
}

}
}```

This program produces same output as of previous program.
