We can declare, instantiate and initialize the java array together by:

int a[]={33,3,4,5};//declaration, instantiation and initialization
Java Program to illustrate the use of declaration, instantiation
and initialization of Java array in a single line
class Testarray1{
public static void main(String args[]){
int a[]={33,3,4,5};//declaration, instantiation and initialization
//printing array
for(int i=0;i<a.length;i++)//length is the property of array
System.out.println(a[i]);
}}

For-each Loop for Java Array
We can also print the Java array using for-each loop. The Java for-each loop prints the array elements one by
one. It holds an array element in a variable, then executes the body of the loop.
The syntax of the for-each loop is given below:

for(data_type variable:array){
//body of the loop
}
Java Program to print the array elements using for-each loop
class Testarray1{
public static void main(String args[]){
int arr[]={33,3,4,5};
//printing array using for-each loop
for(int i:arr)
System.out.println(i);
}}
