declaring an array java code example
Example 1: how to declare array java
int intArray[];
intArray = new int[20];
int[] intArray = new int[20];
Example 2: how to create an array in java
int[] array1 = new int[5];
String[] array2 = new String[5]
double[] array3 = new double[5]
Example 3: java array declaration
int[] array = new int[];
Example 4: how to declare an array in java
An array is an ordered collection of elements of the same type, identified by a pair of square brackets [].
To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
int[] marks;
int marks[];
marks = new int[5];
int[] factors = new int[20];
int[] numbers = {11, 22, 33, 44, 55, 66};
Example 5: java array
int arr[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
int newarr[] = new int[maxSize];
newarr[pos] = n;
for (i = 0; i < maxSize; i++) { newarr[i] = arr[i]; }
Example 6: arrays in java
int[] arr;
arr = new int[N];
