![]() ![]() We also discussed a method of printing multi-dimensional arrays. This tutorial was for printing a one-dimensional array. We have also seen the toString method of Arrays class that converts the array into a string representation and we can directly display the string. In most cases, we need to know when to stop while using loops.įorEach construct of Java is specifically used to traverse the object collection including arrays. Mostly we employ loops to traverse and print the array elements one by one. In this tutorial, we explained the methods that we can use to print arrays. As you can see, it is used to iterate over each element in the array. Q #5) Which technique/loop in Java specifically works with Arrays?Īnswer: The ‘for-each’ construct or enhanced for loop is a loop that specifically works with arrays. But the class ‘Arrays’ from ‘java.util’ package has a ‘toString’ method that takes the array variable as an argument and converts it to a string representation.Īnswer: The fill () method is used to fill the specified value to each element of the array. The elements of the array are enclosed in a square () bracket when displayed using the ‘toString()’ method.Īnswer: There is no direct ‘toString’ method that you can use on an array variable. Q #2) What is the Arrays.toString in Java?Īnswer:‘toString ()’ method returns the string representation of the array that is passed to it as an argument. The entity can be a variable, an array, a list, etc. Frequently Asked QuestionsĪnswer: ‘toString()’ method is used to convert any entity passed to it to a string representation. We will discuss some more methods of printing multidimensional arrays in our tutorial on multidimensional arrays. (epToString(array_2d)) //convert 2d array to string and display ("Two-dimensional Array is as follows:") The program below implements the toString method to print the array. You can then directly print the string representation of the array. ![]() The method ‘toString’ converts the array (passed as an argument to it) to the string representation. The method ‘toString’ belong to Arrays class of ‘java.util’ package. This is the method to print Java array elements without using a loop. Let’s explore the description of these methods. We can also use the loops to iterate through the array and print element one by one. We can convert the array to a string and print that string. To learn more, visit the Java multidimensional array.There are various methods to print the array elements. Here, we have created a multidimensional array named matrix. Example: Access Array Elements class Main , Let's see an example of accessing array elements using index numbers. Here is the syntax for accessing elements of an array, // access array elements We can access the element of an array using the index number.
