Thread: please tell me the code of union and intersection of two arrays without using collections

I have searched on internet but did not find something useful. I do not want to use collections. please help me out!
here's what i have written

class ArrayDemo3
{
	static void union(int x[], int y[])
	{
		System.out.println("Union Elements:");
		for(int i=0; i<x.length; i++)
		{
			for(int j=0; j<y.length; j++)
			{
				if(x[i]!=y[j])
				System.out.println(x[i]);
				//else 
 
			}
		}
	}
	static void intersection(int x[],int y[])
	{
		System.out.println("Intersection Elements:");
		for(int i=0; i<x.length; i++)
		{
			for(int j=0; j<y.length; j++)
			{
				if(x[i]==y[j])
				System.out.println(x[i]);
			}
		}
	}
 
	public static void main(String... kl)
	{
		int p[]={2,5,7,8,5,1};
		int q[]={5,8,2,0,1,6,3};
		union(p,q);
		intersection(p,q);
	}
}
