How do you access array variables?

A Java array variable is declared just like you would declare a variable of the desired type, except you add [] after the type. Here is a simple Java array declaration example: int[] intArray; You can use a Java array as a field, static field, a local variable, or parameter, just like any other variable.

A Java array variable can also be declared like other variables with [] after the data type. The variables in the array are ordered and each have an index beginning from 0. The size of an array must be specified by an int or short value and not long. The direct superclass of an array type is Object.

Array Variables. A variable of array type holds a reference to an object. Declaring a variable of array type does not create an array object or allocate any space for array components. It creates only the variable itself, which can contain a reference to an array.

You do know select value from an array have to specific the index, just don’t know how to use variable expression. Use variables (‘variable_name’) get the variable value and then add the parameter [index] behind it to select the value you want. Just like the below picture shows.

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets: We have now declared a variable that holds an array of strings.

To insert values to it, we can use an array literal – place
