Thread: CompareToIngnore case problem

Okay so here are the two methods I'm having issues with. I need to sort two arrays ingoring case. I thought it would be as simple as chaning the compareTo -->compareToIgnoreCase. But when I do this the compiler tells me

 

SortSearchUtil.java:63: cannot find symbol

symbol  : method compareToIgnoreCase(java.lang.Comparable)

location: interface java.lang.Comparable

						

if(array[searcher].compareToIgnoreCase(array[rs])<0)

Please help

public static int binarySearch(Comparable[]array, Comparable target)
	{
	int min, mid, max;
	min = 0;
	max = array.length-1;
	int found = -1;
	do
	{
		mid =(max+min)/2;
		if(array[mid].compareTo(target)<0)
			min=mid+1;
		else if(array[mid].compareTo(target)>0)
			max=mid-1;
		else
			{found = 1;
			return mid;}
	}while(found == (-1) && min <= max);	
	return found;
	}	
 
 
public static void sortAddresses(Comparable [] array)// class create will own compareto method. geraric
		{
			int ms, rs, searcher;		
			Comparable temp;	
			for(ms = 0; ms<array.length-1; ms++)
				{
					rs = ms;
					for(searcher = ms+1; searcher<array.length;searcher++)
					{	
						if(array[searcher].compareToIgnoreCase(array[rs])<0)//based on the type of the object making the call.
						rs = searcher;
					}
					temp = array[ms];
					array[ms] = array[rs];
					array[rs] = temp;				
				}
			}//end method

Here is the comparable interface javadoc: Comparable (Java Platform SE 6)

Does the method you are trying to use actually exist?

Sorry for the cross post... I am new to using these sites.

On the other forum, I have reported this cross poster for its abusive response which is a clear violation of the terms of use of that site.

edit Another abusive response on the other thread, also reported.

Abuse reported. Violations of the terms of use are not tolerated on any forum.

Ok, I hate to say it but, Darryl.Burke Darryl.Burke, you're starting to overdue it.

Sometimes it can take a while to get an answer. I've been there. People sometimes need help and may care more about getting a bad grade due to long response time than they do about the rules of some fourm, not this forum by the way.

[error] what does this do?

Ok, how did you get that error message block?
