Texturing problems with Blender .obj models

[Vinz321]

Hello everyone, I'm a young developer, it's the first time I work with a 3d project;
Following a youtube tutorial I wrote an OBJLoader, but with the model I made with blender the textures are all misplaced;
I have another model, a stall that loads perfectly, I can't understand if the problem are the models or the program.

public static RawModel loadOBJModel(String filename,Loader loader)
	{
		FileReader fr=null;
		try {
			fr=new FileReader(new File("src/sources/"+filename+".obj"));
		} catch (FileNotFoundException e) {
			System.err.println("COuld not read");
			e.printStackTrace();
		}
		BufferedReader reader=new BufferedReader(fr);
		String line;
		List<Vector3f> vertices=new ArrayList<Vector3f>();
		List<Vector2f> texture=new ArrayList<Vector2f>();
		List<Vector3f> normals=new ArrayList<Vector3f>();
		List<Integer> indices=new ArrayList<Integer>();
		
		float[] vertexArray=null;
		float[] texturesArray=null;
		float[] normalsArray=null;
		int[] indicesArray=null;
	try {
		while(true)
		{
			
			line=reader.readLine();
			String[] currentLine=line.split(" ");
			if(line.startsWith("v "))
			{
				Vector3f vector=new Vector3f(Float.parseFloat(currentLine[1]),Float.parseFloat(currentLine[2]),Float.parseFloat(currentLine[3]));
				vertices.add(vector);
			}
			else if(line.startsWith("vt "))
			{
				Vector2f tex=new Vector2f(Float.parseFloat(currentLine[1]),Float.parseFloat(currentLine[2]));
				texture.add(tex);
			}
			else if(line.startsWith("vn "))
			{
				Vector3f normal=new Vector3f(Float.parseFloat(currentLine[1]),Float.parseFloat(currentLine[2]),Float.parseFloat(currentLine[3]));
				normals.add(normal);
			}
			else if(line.startsWith("f "))
			{
				texturesArray=new float[vertices.size()*2];
				normalsArray=new float[vertices.size()*3];
				break;
			}
		}
		
		while(line!=null)
		{
			if(!line.startsWith("f "))
			{
				line=reader.readLine();
				continue;
			}
			
			String[] currentLine=line.split(" ");
			String[] vertex1=currentLine[1].split("/");
			String[] vertex2=currentLine[2].split("/");
			String[] vertex3=currentLine[3].split("/");
			
			processVertex(vertex1,indices,texture,normals,texturesArray,normalsArray);
			processVertex(vertex2,indices,texture,normals,texturesArray,normalsArray);
			processVertex(vertex3,indices,texture,normals,texturesArray,normalsArray);
			line=reader.readLine();
			}
		reader.close();
		
	}
		catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
	
	    vertexArray=new float[vertices.size()*3];
	    indicesArray=new int[indices.size()];
	    
	    int vertexPointer=0;
	    
	    for(Vector3f vector:vertices)
	    {
	    	vertexArray[vertexPointer++]=vector.x;
	    	vertexArray[vertexPointer++]=vector.y;
	    	vertexArray[vertexPointer++]=vector.z;
	    }
	    for(int i=0;i<indices.size();i++)
	    {
	    	indicesArray[i]=indices.get(i);
	    }
	    
	    RawModel model=loader.loadToVAO(vertexArray,texturesArray,normalsArray, indicesArray);
	    return model;
		
	}
	
	public static void processVertex(String[] vertexData,List<Integer> indices,List<Vector2f> tex,
			List<Vector3f> normals,float[] textureArray,float[] normalsArray)
	{
		int currentVertexPointer=Integer.parseInt(vertexData[0])-1;
		
		indices.add(currentVertexPointer);
		Vector2f currentTex=tex.get(Integer.parseInt(vertexData[1])-1);
		textureArray[currentVertexPointer*2]=currentTex.x;
		textureArray[currentVertexPointer*2+1]=1-currentTex.y;
		Vector3f currentNorm=normals.get(Integer.parseInt(vertexData[2])-1);
		normalsArray[currentVertexPointer*3]=currentNorm.x;
		normalsArray[currentVertexPointer*3+1]=currentNorm.y;
		normalsArray[currentVertexPointer*3+2]=currentNorm.z;
		
	}

This is the code, can anyone help me?

I resolved my problem
To help someone with my same problem:
I used edge split in blender and splitted sharp edges after unwrapping the model

Hi I'm glad you solved your issue. I'm also having the same problem. Could you elaborate on what you did in blender?
