Convert Array to List
Let's write a Java program to convert Array to List:
package net.javaguides.hibernate;
import java.util.Arrays;
import java.util.List;
public class ConvertArrayToListExample {
public static void main(String[] args) {
List<Integer> sourceList = Arrays.asList(0, 1, 2, 3, 4, 5);
// convert List to array
Integer[] targetArray = sourceList.toArray(new Integer[sourceList.size()]);
// print set
System.out.println(Arrays.toString(targetArray));
}
}
Output:
[0, 1, 2, 3, 4, 5]
Convert List to Array
Let's write a Java program to convert List to Array:
package net.javaguides.hibernate;
import java.util.Arrays;
import java.util.List;
public class ConvertArrayToListExample {
public static void main(String[] args) {
Integer[] sourceArray = {
0,
1,
2,
3,
4,
5
};
// convert array to list
List < Integer > targetList = Arrays.asList(sourceArray);
// print list
targetList.forEach(value - > System.out.println(value));
}
}
Output:
0
1
2
3
4
5
