示例1: compileShader
import javax.media.opengl.GL2; //導入方法依賴的package包/類
/**
* Compile a shader from a file.
*
* @param context Class context for loading the resource file.
* @param gl GL context
* @param type
* @param name
* @return Shader program number.
* @throws ShaderCompilationException When compilation failed.
*/

// This worked best for me to capture error messages:

// Different way of catching errors.

@Override
public void free(GL2 gl) {
