help with mergesort

[desconocido]

hi,
im trying to do a mergesort algorithm with random numbers
i know i need to divide the array into other 2 until i got ordered arrays(or 1 and 0 length arrays) that part works great
but when i try to order (with a length of 2 or more) theres almost always an error of array out of bounds, maybe i forgot something?
heres my meth

public static int[] order(int b[], int c[]){
		int a[]=new int[(b.length)+(c.length)];
		int i=0;
		int j=0;
		for(int k=0;k<((b.length)+(c.length));k++){
			if((b[i]<=c[j] && i !=b.length && j !=c.length) || (i !=b.length && j ==c.length)){
				a[k]=b[i];
				i=i+1;
			}if((b[i]>c[j] && i !=b.length && j !=c.length) || (i ==b.length && j !=c.length)){
				a[k]=c[j];
				j=j+1;
			}
		}
		return a;
	}

please help!

error of array out of bounds

What array, what variable, what line of code and what is the index's value.

it says line 10,but thats

if((b[i]<=c[j] && i !=b.length && j !=c.length) || (i !=b.length && j ==c.length)){

thats why i was thinking if there is other case i didnt write

That's one part where are the other three:
What array, what variable, what line of code and what is the index's value.

Interesting placement of } and if. Was that intentional?

}if((b[i]>c[j]

i dont know witch array/variable may be
and index value is variable

Add some print outs to show the values of the variables.
The error message will show the index value that is out of range.
