[SOLVED] Arrays/for-loops (easy) need help.

[Zebra]

Hey I am suppose to rewrite the following code but make it so that the array is initialized on one line of code and a loop is used to display for the results.

Code:

class OneDimensionArray {

	public static void main(String args[]) {
	// Declare and allocate space
	int myarray[] = new int[4];
	// Initialize elements
	myarray[0] = 33;
	myarray[1] = 71;
	myarray[2] = -16;
	myarray[3] = 45;
	// Display length
	System.out.println("myarray.length = " +
	myarray.length);
	// Display elements
	System.out.println(myarray[0]);
	System.out.println(myarray[1]);
	System.out.println(myarray[2]);
	System.out.println(myarray[3]);
	}
}

[Java Tip]

It is easy. Check array initialization part of Java tutorial again and use one println statement inside a for loop where array index is replaced with loop control variable!

Well said!

Zebra, should this solve your answer, please mark this thread as solved- if not, post back your updated code and we'll assist you.

Yep, don't have any feedback from Zebra on what JavaTip and Captain says. It's not a difficult one. JavaTip gives all the details there.

So where do I put the for-loop. Sorry?

hello zebra,

As you have told that you are fresher, then my advise is to read some core java fundamentals books and do some research on programs . If you do something at your own then you will learn more. and one more thing do more and more practice on core java. CORE JAVA IS THE TOUGHEST part in Java language, Once you grab good knowledge on core part you will not get difficulty on other parts like servlets,jsp etc.

well for now i think you require this.

Code:

class OneDimensionArray {

	public static void main(String args[]) {
		// Declare and allocate space
		int myarray[] = new int[]{33,71,-16,45};
		// Initialize elements
		// Display length
		System.out.println("myarray.length = " + myarray.length);
		// Display elements
		for (int i=0;i<myarray.length;i++ ){
			System.out.println(myarray[i]);
		}
	}
}

Thank you very much! I am in a java programming I class and he tries to just teach us, without books and stuff. But, thanks again. I will research.

You got the answer It's not difficult pal. Read more about and do some experiment yourself.
