public class BirdArray {
public static void main(String args[]){
String[] str = new String[]{" The sparrow "," The eagle "," dove "," yellowbird "," The lark "," The peacock "," The parrot "," Red-crowned cranes "};
int index =0; //Create index variables
System.out.println(" There are many kinds of birds in the park :");
while(index<str.length){ //Through the array
System.out.println(str[index++]); //Self-incrementing index value
}
}
}
Output:
run:
There are many kinds of birds in the park :
The sparrow
The eagle
dove
yellowbird
The lark
The peacock
The parrot
Red-crowned cranes
BUILD SUCCESSFUL (total time: 0 seconds)
Conclusion:
Create an index variable, index, that specifies the index of the array, and as the index increases, the while loop iterates through each element and outputs it to the console. Notice the difference between ++index and index++.
++index: increments the value of index and then USES the incremented value.
Index++ : first use the value of index and then increment the value of the variable.
