non-static variable this cannot be referenced from a static context

[Ashish Maharaja Singh]

please tell me the error in my concepts. I am get this error on line "TempArray ta = new TempArray(le,ri);"

public class Test
{
	static int[]given = {7,4,2,8,1,9,3,10,6,5,11};
	
	public static void main(String[]args)
	{
		do(given);		
		
	}

	public static void do(int[]take)
	{
		int le = 1 + (size-1)/2; 
		int ri = size-l;
		TempArray ta = new TempArray(le,ri);		
		ta.show();
	}

	class TempArray
	{
		int[]Le; 
		int[]Ri; 
		TempArray(int le, int ri)
		{
			this.Le = new int[le];
			this.Ri = new int[ri];
			
		}
	}
}

Hi Ashish,

Welcome to JavaRanch
Please use code tags while posting question it simple just select your code and click on Code tag in the window where you are writing Question

The problem is that TempArray is an inner class of Test. Therefore you need an instance of Test to create an instance of TempArray.
You can make TempArray a not-inner class or use an instance of Test to create a TestArray: new Test().new TestArray();

And welcome to the JavaRanch.

And of course posting the error message would help.

My guess is that since TempArray is not declared as static the compiler is complaining that you are trying to access it in a static context.

Edit: :-) I'm so slow!

thanks ! that was a bad error on my part.

}

i think its because you did not declare size and TempArray variables..and another fault i see is class TempArray does not have a method named "Show"
