Video: Java Reflection Tutorial: Accessing Array ElementsPaul Anderson
This section describes how to access array elements for assigning new values and retrieving existing values. 'For Each' statement can also be used to loop through all elements in an array. If you want to access a specific element of an array, you need to use the array element syntax, whic...
Like many other programming languages, an array element can be accessed with the array element syntax of array_name[index]. An array index starts with 0. The length of an array is defined as the highest index of all elements plus 1. There is no index-out-of-bound exception in ...

The enumerate() function can be used to access elements of an array. It accepts an array and an optional starting index as parameter values and returns the array items by iterating. ExampleIn the below example, we will see how to use the enumerate() function to access array items. ...
int ArraySize = taskItems.size(); if (ArraySize >getCurrentTaskId()+1) { System.out.println("IN" + getCurrentTaskId()); setCurrentTaskId(getCurrentTaskId()+ 1 ); System.out.println("OUT" + getCurrentTaskId()); } System.out.println( "No more tasks" ); } public void addTa...

If you have experience with other programming languages, you must have noticed a significant difference in the way we number the positions inan array. While in C/C++, for example, numbering the elements of an N x 1 array starts with 0 and ends at N-1, MATLAB uses values from 1 to N...
Caution: You should never modify the R.java file by hand—it is generated by the aapt tool when your project is compiled. Any changes are overridden next time you compile. Accessing Resources from XML You can define values for some XML attributes and elements using a reference to an existing...
