This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hello! I'm incredibly new to Java and programming. The problem I'm having with this piece of code is the marked for loop (or at least I think it is), I want it to take all all elements below 10 and copy them into array10 but it just isn't doing that and I'm not sure where I've gone wrong. Help would be brilliant Thanks.
In your MARKED for loop, x is not the value of an array element - it's the index of an array element. The value is represented by randArray[x].
Also, you don't need to use system.arraycopy to copy a single array element. Just use
And just for the record, your parameters to System.arraycopy are wrong. The last parameter is the number of values to copy, so the first time round the loop you copied none, the second time one, the third time two, etc
