Convert string to char array

In programming, a string is a sequence of characters that is represented as a single data type. A char array, on the other hand, is an array of characters where each element in the array is a single character.

To convert a string to a char array, you need to break down the string into its individual characters and store them in an array of characters. This process is known as "string to char array conversion".

Program Solution

/*
    Java program for
    Convert string to char array
*/
public class Conversion
{
	public void printArray(char[] ans, int n)
	{
		for (int i = 0; i < n; ++i)
		{
			System.out.print(" " + ans[i]);
		}
		System.out.print("\n");
	}
	public static void main(String[] args)
	{
		Conversion task = new Conversion();
		// Given text
		String str1 = "abcde";
		String str2 = "1b2c3d4e";
		// Get the length of string
		int n1 = str1.length();
		int n2 = str2.length();
		// Case A
		char[] ans1 = str1.toCharArray();
		// Case B
		char[] ans2 = new char[n2];
		for (int i = 0; i < n2; ++i)
		{
			ans2[i] = str2.charAt(i);
		}
		// Display result
		task.printArray(ans1, n1);
		task.printArray(ans2, n2);
	}
}

Output

	}
};
