What will be the equivalent java code for this C# code?

[Noob1234]

I am making a web based stagenography appplication in java but i am stuck at how to get the individual values of Red Green and Blue in an image pixel.I have an equivalent code in C# but i am not able to split a pixel value into Red,Green and blue.

The following code includes the function that hides the picture in another image.

private void hide_image()
    {
        string file = openFileDialog1.FileName;
        original = (Bitmap)Bitmap.FromFile(file);
 
        Color color,color1, color2, color3;
        int value;
        int r1, b1, g1, a1;
        int pixelR, pixelG, pixelB, pixelA;
        for (int i = 0; i < original.Width; i++)
        {
            for (int j = 0; j < original.Height; j++)
            {
                color = bmp.GetPixel(i, j);
                color2 = original.GetPixel(i, j);
                r1 = color2.R;
                b1 = color2.B;
                g1 = color2.G;
                a1 = color2.A;
 
                value = color.R;
 
                byte[] array = getBytes(value);
                byte[] arrayR1 = getBytes(r1);
                byte[] arrayG1 = getBytes(g1);
                byte[] arrayB1 = getBytes(b1);
                byte[] arrayA1 = getBytes(a1);
 
                arrayR1[6] = array[0];
                arrayR1[7] = array[1];
                arrayG1[6] = array[2];
                arrayG1[7] = array[3];
                arrayB1[6] = array[4];
                arrayB1[7] = array[5];
                arrayA1[6] = array[6];
                arrayA1[7] = array[7];
 
                pixelR = getInt(arrayR1);
                pixelG = getInt(arrayG1);
                pixelB = getInt(arrayB1);
                pixelA = getInt(arrayA1);
                color3 = Color.FromArgb(pixelA, pixelR, pixelG, pixelB);
                original.SetPixel(i, j, color3);
            }
        }
        pictureBox4.Image = original;
 
      }

In C# i am using color object to get the separate the values of RGB.How will i get those in java?
