Array getChar() Method in Java

Last Updated : 23 Nov, 2022

The java.lang.reflect.Array.getChar() is an inbuilt method in Java and is used to return the element present at a given index from the specified Array as a char. Syntax

Array.getChar(Object []array,int index)

Parameters :

array : The object array whose index is to be returned.
index : The particular index of the given array. The element at 'index' in the given array is returned.

Return Type: This method returns the element of the array as char. Note: Typecast isn't necessary as the return type is char Exception: This method throws following exception

NullPointerException – when the array is null.
IllegalArgumentException – when the given object array is not an Array.
ArrayIndexOutOfBoundsException – if the given index is not in the range of the size of the array.

Below programs illustrate the getChar() method of Array Class: Program 1:

Java

// Java code to demonstrate getChar() method of Array class import java.lang.reflect.Array; public class GfG  {     // main method     public static void main(String[] args) {                 // Declaring and defining an byte array        char a[] = {'G','f','G'};                // Traversing the array        for(int i = 0;i<3;i++){                        // Array.getChar() method                        char x = Array.getChar(a, i);            // Printing the values            System.out.print(x);        }              } }

Output:

GfG

Program 2:

Java

// Java code to demonstrate getChar() method in Array import java.lang.reflect.Array;   public class GfG {       // main method     public static void main(String[] args) {         // Declaring and defining an char array         char a[] = {'G','f','G'};           try {             // invalid index             char x =  Array.getChar(a, 6);             System.out.println(x);         } catch (Exception e) {             // throws Exception             System.out.println("Exception : " + e);         }     } }

Output:

Exception : java.lang.ArrayIndexOutOfBoundsException

Program 3:

Java

// Java code to demonstrate getChar() method in Array import java.lang.reflect.Array;   public class GfG {       // main method     public static void main(String[] args) {         // Declaring and defining an char array to null         char a[] = null;           try {             // null Object array             char x =  Array.getChar(a, 6);             System.out.println(x);         } catch (Exception e) {             // throws Exception             System.out.println("Exception : " + e);         }     } }

Output:

Exception : java.lang.NullPointerException

Program 4:

Java

// Java code to demonstrate getChar() method in Array import java.lang.reflect.Array;   public class GfG {       // main method     public static void main(String[] args) {         // Declaring and defining an char variable         char a = 'a';           try {             //illegal Argument             char x =  Array.getChar(a, 6);             System.out.println(x);         } catch (Exception e) {             // throws Exception             System.out.println("Exception : " + e);         }     } }

Output:

Exception : java.lang.IllegalArgumentException: Argument is not an array
