مساعده في تحويل من ascii to hex

طريقة التحويل من ASCII إلى hex

------------------------------------------------

String myStr = "Hello World";
        StringBuffer hex = new StringBuffer();
char[] myChar = myStr.toCharArray();
        for (int i = 0; i < myChar.length; i++) {
            hex.append(Integer.toHexString(myChar));
        }
        System.out.println(hex);

طريقة التحويل من Hex إلى ASCII

-------------------------------------------------

سوف نستخدم ناتج ال hex السابق و نحوله إلى ASCII

StringBuilder sb = new StringBuilder();
      for (int i = 0; i < hex.length() - 1; i += 2) {
            String output = hex.substring(i, (i + 2));
            int decimal = Integer.parseInt(output, 16);
            sb.append((char) decimal);
        }
        System.out.println("Hex to ASCII" +" >>>>>>> "+ sb.toString());

الكود كاملاً :

=========

public class TestConvert {
      private StringBuffer hex = new StringBuffer();
 private StringBuilder sb = new StringBuilder();
     private StringBuilder temp = new StringBuilder();

      private String myStr = "Hello World";

    public TestConvert() {
        char[] myChar = myStr.toCharArray();
        for (int i = 0; i < myChar.length; i++) {
            hex.append(Integer.toHexString(myChar));
        }
        System.out.println("ASCII to HEX" + " >>>>>> " + hex);
        ///////////////////////////////////////////////////////
        for (int i = 0; i < hex.length() - 1; i += 2) {
            String output = hex.substring(i, (i + 2));
            int decimal = Integer.parseInt(output, 16);
            sb.append((char) decimal);
            temp.append(decimal);
        }
        System.out.println("Decimal" + " >>>>>>> " + temp.toString());
        System.out.println("Hex to ASCII" +" >>>>>>> "+ sb.toString());
    }

    public static void main(String[] args) {
        new TestConvert();
    }
}
