Return type doubt

[saloni jhanwar]

There is compile error in below program "Incompatible type", how to resolve it without changing return type "Object" for method "returnArray".

class Test 
{
	Object returnArray()
	{
		return new int[] {1,2,3};
	}
	public static void main(String[] args) 
	{
			Test obj=new Test();
			int[] x=obj.returnArray();
			for(int y:x)
			{
				System.out.println(y);
			}
	}
}

You cannot do without adding an explicit cast.

Tried, but i think there is syntax problem

class Test 
{
	Object returnArray()
	{
		return new int[] {1,2,3};
	}
	public static void main(String[] args) 
	{
			Test obj=new Test();
			Object obj=obj.returnArray();
			int[] x=(int[])obj;
			for(int y:x)
			{
				System.out.println(y);
			}
	}
}

You should typecast it during the assignment itself :

int[] x= (int [])obj.returnArray();

Please refer to my next post

By the way, in your second code, I see two references with same name obj

This would also work:

Object object = obj.returnArray();
int[] x = (int [])object;

Thanks

You are welcome.

By the way, its not necessary to typecast it during the assignment. Only problem with your second code was duplicate variable name.
