Code:

public class FileStructure {
	public static void main(String[] args) throws Exception {
		Object data[] = new Object[150];
		
		for(int i = 0 ; i < 150 ; i ++){
			data[i] = (short)43 ; // It is just an example
			/*
			 * Autoboxing allows you to add any primitive char and bytes ... 
			 */
		}
		
		for(int i = 0 ; i < 150 ; i ++){
			if(data[i] instanceof Short ){
				System.out.println("Short Data :" + data[i]);
			}
			
			// Similarly you can check with other primitive Wrappers  ..
		}
	}
}
