Java String copyValueOf() method

copyValueOf() method returns a String that holds the character sequence of the character array.

Syntax:

copyValueOf(char[] data)

Parameters:

data : the character array i.e. String

Returns:

It returns a String that contains the characters of the character array.

Java String copyValueOf() Example 1:

public class JavaCopyValueOfEx1 {
   public static void main(String args[]) {
       char[] data = {'a','b','c','d','e','f','g','h','i','j','k'};
       String str1 = "Text";   
       str1 = str1.copyValueOf(data);
       System.out.println("str1 after copy: " + str1);
   }
}

Output:

str1 after copy: abcdefghijk

Java String copyValueOf() Example 2:

public class JavaCopyValueOfEx2 {
   public static void main(String args[]) {
       char[] data = {'a','b','c','d','e','f','g','h','i','j','k'};
       String str1 = "Text";
       String str2 = "String";
       //Variation 1:String copyValueOf(char[] data)
       str1 = str1.copyValueOf(data);
       System.out.println("str1 after copy: " + str1);
       //Variation 2:String copyValueOf(char[] data,int offset,int count)
       str2 = str2.copyValueOf(data, 5, 3 );
       System.out.println("str2 after copy: " + str2);
   }
}

Output:

str1 after copy: abcdefghijkstr2 after copy: fgh

Java String copyValueOf() Example 3:

public class JavaCopyValueOfEx3
{
public static void main(String[] args)
    {
        // Character array with data.
char[] arr_num = new char[] { '1', '2', '3', '4', '5', '6', '7', '8', '9' };
        // Create a String containig the contents of arr_num
        // starting at index 1 for length 2.
        String str = String.copyValueOf(arr_num, 4, 3);
        // Display the results of the new String.
System.out.println("\nThis Java Book contains  " + str +" pages.\n");
    }
}

Output:

This Java Book contains  567 pages.

Java String copyValueOf() Example 4:

public class JavaCopyValueOfEx4 {
  public static void main(String args[]) {
       // Initialising Character array
     char[] ch = {'R', 'O', 'Y', ' ', 'N', 'I', 'T', 'I', 'S', 'H'};
      // Initialising String
     String ch2 = "";    
     // Copying value in ch2
     // now ch2 is equal to "ROY NITISH"
     ch2 = ch2.copyValueOf( ch );     
     // Printing String
     System.out.println("copied string is : " + ch2);
  }
}

Output:

copied string is : ROY NITISH
