    The contents of an array must be all of the same type; for example all int or all String.
    Since all classes extend the Object class, an array of Object would be able to hold references to any class, but NOT any primitives like int or char.

    Why do you want to have mixed types in an array?
    If you don't understand my answer, don't ignore it, ask a question.

    Simply, wrap the data in a class like this:

    class Mix {
    	private int number;
    	private String word;
     
    	public Mix(int number, String word){
    		this.number = number;
    		this.word = word;
    	}
     
    	public void setNumber(int number) {
    		this.number = number;
    	}
     
    	public int getNumber() {
    		return this.number;
    	}
     
    	public void setWord(String word) {
    		this.word = word;
    	}
     
    	public String getWord() {
    		return this.word;
    	}
    }
     
    class Main {
    	public static void main(String[] args) {
    		Mix[] mixArray = { new Mix(1, "X"), new Mix(2, "Y"), new Mix(3, "Z") };
    		for(Mix mix : mixArray) {
    			System.out.println("number=" + mix.getNumber() + ",word=" + mix.getWord());
    		}
    	}
    }
