System.out.println( Arrays.toString( array ) );
The Arrays object from the java.util library formats the content of an Array into a human readable String. That String can be written in the output or the logs.
This example creates an Array of String containing three elements. The array is converted to a String using Arrays.toString. The output is written in the logs.
import java.util.Arrays;
public class PrintArray {
public static void main(String[] argv) {
final String[] tab = {"San Francisco","Los Angeles","New York"};
System.out.println( Arrays.toString( tab ) );
}
}
[San Francisco, Los Angeles, New York]
If the Array is not converted to a String, the address in memory of the Array is written in the logs.
