In the latter example, you specified the elements while creating the array. This saved you from writing additional instructions for assigning values to the elements. That’s the benefit of creating an array this way. Alternatively, you can create code to populate the elements with each new eleme...
In method1(), we create three local variables and assign them with values, now we create an array of type String called array1. Now we set the indexes of array1 with the variables. Then we return the array using return array1. In the main() method, we call method1() and convert ...
Direct initialization during declaration is one of the simplest ways to create a 2D array in Java. This method allows developers to define the array and assign values to its elements in a concise manner. To create a 2D array using direct initialization, we simply declare the array variable and...
Even though Java makes work so easy with arrays, you can make it even easier by using array initializers. These magical things create arrays without using the new keyword, allowing you to declare an array reference, instantiate an array, and fill the array with elements all in a single state...
