Please print out the hexadecimal form of a decimal integer by shifting. Tip: The integer is shifted and debited every 4 binary digits, and the result is a hexadecimal number. Then use one of the following three methods (As a job, each method is required ) Calculate the hex form of a hexadecimal value:
1) The value between 0-9 is directly added to the character '0', and the value above 9 is subtracted from 10 and then the character 'A' is added
2) Define an array that contains the characters 0-F, and then use the value to be calculated as the index number of the array to obtain its corresponding hexadecimal data.
3) The Character.forDigit static method can convert a hexadecimal number to its corresponding character representation, for example, returns the character 'F' based on the value 15.

It's not difficult or annoying. I don't know which step of LZ ~~ Don't throw a big question out.

Is a bit annoying

Is decimal to hexadecimal?

public class DecToHex {

public static char table[]={'0','1','2','3','4','5','6','7','8','9','A ','B','C','D','E','F'};

    public static void main(String[] args)
    {
    int sourceDec=Integer.parseInt(args[0]);
    int length=0;
    int[] digits=new int[20];
    while(sourceDec>=16)
    {
    digits[length++]=sourceDec%16;
    sourceDec/=16;
    }
    digits[length]=sourceDec;
    for(int i=length;i>=0;i--)
    {
    System.out.print(table[digits[i]]);
    }
    }

}

Such things are annoying to watch.
