I'm trying to code a method in Java that returns true or false, depending on if a supplied string matches any word in an array list, but I think there's a simpler way to do it, than I am. What I have is

public boolean isKnownWord(String word)
{
boolean trueOrFalse = false;
for(String testWord: words)
{
if(testWord.equalsIgnoreCase(word))
{
trueOrFalse = true;
}
}
return trueOrFalse;
}

Can anyone help?

I didn't think 5 year olds were allowed near a computer. Might spill their spaghetti hoops and milk on it.

Java makes me nauseous.

I figured all the ass bandits were too busy sucking cocks to have time to reply. No need to take out your homosexual frustrations on me, could've just told me that I had the wrong board.

public boolean isKnownWord(String n)
{
for(String h: words)
if(n.equalsIgnoreCase(h))
return true;
return false;
}

There are more efficient ways, though.

Also, Java sucks.

Yeah. I'm finding that it's a pain in the ass, but I have to take it before I can take any other COSC classes. Thank you, that worked perfectly.

Why the fuck would you EVER do that shit?

Code in a real language or get the fuck out

Some retard actually supports java? The fuck

Nope, I don't like it myself. But I'm sick of these endless discussions.

The unanimous consensus is that java is garbage and only exist because computer science majors are too retarded to understand real languages or *gasp* unsigned/complex numbers.

>>5604556
What the fuck does Java have to do with complex numbers?

[Anonymous No.5604589]

>>5604318
run through your arraylist with a for loop, and just keep matching, if found return true else return false. Isn't hard, are you 10?

And now look what he did (in some lines of code more than necessary, true that).
What the fuck is wrong with you?

doesn't support complex data types, doesn't support unsigned data types, doesn't support pointers, doesn't support operator overloading, doesn't support goto, doesn't even support basic coding constructs like "if(x){...}"

Then use recursion.
public boolean foo (ArrayList a)
if a.length == 0
return false;
if (a.elementAt(0).equals(word))
return true;
return foo(rangeOf(1, length);

API for the method names

public boolean isKnownWord(String word) {
return (words.indexOf(word) != -1);
}

Oh, wait. That is case sensitive.

You guys are retarded. Use the right language for the problem you're trying to solve. Need cross platform support? Javas a fairly decent choice.

But by being "hurr durr java is bad cos i heard someone say it is slow so im not gonna use it" is only limiting your choices and making you a worse developer in the process.

Don't get me wrong, I'm not saying you should be using Java all the time. I haven't touched it over a year. But you should always keep an open mind and consider every option when trying to solve a problem.
