[Solved] Could you tell me why textured cube is rendered oddly?

[Harang]

I'm studying LWJGL3 with '3D Game Development with LWJGL3', and I made a textured cube as reading the Chapter7 of the book.
However, I was so puzzled after seeing my cube. The cube was distorted. Could you tell me why my cube is rendered oddly?

// This is the VAO of the cube.
                  float[] positions = new float[]{
            -0.5f, 0.5f, 0.5f,      // V0
            -0.5f, -0.5f, 0.5f,    // V1
            0.5f, -0.5f, 0.5f,     // V2
            0.5f, 0.5f, 0.5f,      // V3
            -0.5f, 0.5f, -0.5f,  // V4
            0.5f, 0.5f, -0.5f,   // V5
            -0.5f, -0.5f, -0.5f,  // V6
            0.5f, -0.5f, -0.5f,    // V7
            
            // Top 4503
            -0.5f, 0.5f, -0,5f,    // V8
            0.5f, 0.5f, -0.5f,     // V9
            -0.5f, 0.5f, 0.5f,     // V10
            0.5f, 0.5f, 0.5f,      // V11
            
            // Right 3 2
            0.5f, 0.5f, 0.5f,     // V12
            0.5f, -0.5f, 0.5f,   // V13
            
            // Left 0 1
            -0.5f, 0.5f, 0.5f,    // V14
            -0.5f, -0.5f, 0.5f,   // V15
            
            // BOTTOM 6712
            -0.5f, -0.5f, -0.5f,    // V16
            0.5f, -0.5f, -0.5f,     // V17
            -0.5f, -0.5f, 0.5f,     // V18
            0.5f, -0.5f, 0.5f,      // V19
      };
      float[] textCoords = new float[] {
            0.0f, 0.0f,
            0.0f, 0.5f,
            0.5f, 0.5f,
            0.5f, 0.0f,
            
            0.0f, 0.0f,
            0.5f, 0.0f,
            0.0f, 0.5f,
            0.5f, 0.5f,
            
            // Top
            0.0f, 0.5f,
            0.5f, 0.5f,
            0.0f, 1.0f,
            0.5f, 1.0f,
            
            // Right
            0.0f, 0.0f,
            0.0f, 0.5f,
            
            // Left
            0.5f, 0.0f,
            0.5f, 0.5f,
            
            // Bottom
            0.5f, 0.0f,
            1.0f, 0.0f,
            0.5f, 0.5f,
            1.0f, 0.5f,
      };
      int[] indices = new int[] {
            // Front
            0, 1, 3, 3, 1, 2,
            // Top
            8, 10, 11, 9, 8, 11,
            // Right
            12, 13, 7, 5, 12, 7,
            // Left
            14, 15, 6, 4, 14, 6,
            // Bottom
            16, 18, 19, 17, 16, 19,
            // Back
            4, 6, 7, 5, 4, 7,
      };

I don't have any idea about how I can solve this problem.
Please help me. X(

You just have a comma where you need a stop:

-0.5f, 0.5f, -0,5f,    // V8
goes to:
-0.5f, 0.5f, -0.5f,    // V8

Oh and welcome to the LWJGL forum

I guessed that my code had several differences compared with a example code, but I didn't know that the problem was very simple like this.
The foot of the candle was dark. Thank you so much!
