Thread: Iterating through an ArrayList to view its contents

Yeah, I'm trying to figure out how to print the elements of an array list in a non-static way. Here's the array list function definition class:

package samsExperiments;
import java.util.ArrayList;
 
public class SamsArrays {
 
	public static ArrayList<String> samsStaticArrayList() {
		ArrayList x = new ArrayList();
		x.add("A");
		x.add("B");
		x.add("C");
		x.add("D");
		return(x);		
	}
 
	public ArrayList<String> samsArrayList() {
		ArrayList x = new ArrayList();
		x.add("A");
		x.add("B");
		x.add("C");
		x.add("D");
		return(x);		
	}
}

And here's the class with the main method:

package samsExperiments;
 
import java.util.Scanner;
import java.util.Arrays;
import java.util.ArrayList;
import java.util.Random;
 
import static samsExperiments.StaticMethodExample.*;
 
import java.lang.StringBuilder;
import java.text.DecimalFormat;
import java.util.Arrays;
import java.util.InputMismatchException;
 
import customExceptions.IntegerOutOfRangeException;
 
public class SamsExperimentsMain {
 
	public static void main(String[] args){
 
		SamsArrays.samsStaticArrayList();//call a static method
 
		SamsArrays sams = new SamsArrays();
		ArrayList<String> x = sams.samsArrayList();
 
		for(int i = 0; i < x.length(); i++) {
			System.out.println(x[i]);
		}		
	}
}

The error on line 26 says, "The method length() is undefined for the type ArrayList<String>".
The error on line 27 says, "The type of the expression must be an array type but it resolved to ArrayList<String>".

How do I fix this?

Problem Solved!

public ArrayList<String> samsArrayList() {
		ArrayList x = new ArrayList();
		x.add("A");
		x.add("B");
		x.add("C");
		x.add("D");
		return(x);		
	}
	/*
	//How to call it in the main method
	SamsArrays sams = new SamsArrays();
	ArrayList<String> x = sams.samsArrayList();
 
	for(String str:x) {
		System.out.println(str);
	}
