This blog helps to convert Java String to a character array.
1. Logical Approach without any inbuilt functions.
Follow these steps:
- Create a String variable and assign a value.
- Use the length of the String variable to create an array of characters.
- Use a loop to iterate the String using an index.
- Assign a value at the index to a character array.
- Once loops complete, Characters array will be ready to use.
- Use a loop to print the character array.
Code:
public class StringToCharArray {
public static void main( String args[] )
{
//1. Create a String variable and assign a value
String cbm = "CodeBlogMoney";
int lengthOfString = cbm.length();
//2.Use the length of the String variable to create an array of characters
char[] arrayOfCharacters = new char[ lengthOfString ];
// 3. Use a loop to iterate the String using an index.
for ( int i = 0; i < lengthOfString; i++ ) {
// 4 Assign a value at the index to a character array.
arrayOfCharacters[i] = cbm.charAt(i);
} // 5. Once loops complete, Characters array will be ready to use.
// 6. Use a loop to print the character array
for ( char valueofChar : arrayOfCharacters ) {
System.out.println( valueofChar );
}
}
}
Output of above code:
C o d e B l o g M o n e y
2. Using toCharArray() function
java.lang.String has toCharArray() which converts String to array of characters and return the new object of array.
Follow these steps
- Define a string object with value.
- Use toCharArray() to return the array of characters
- Print the values of the character of array.
Code
public class StringToCharArrayUsingInbuildMethod {
public static void main( String args[] )
{
//1. Define a string object with value
String cbm = "CodeBlogMoney";
//2.Use toCharArray() to return the array of characters
char[] arrayOfCharacters = cbm.toCharArray();
// 3. Print the values of the character of array.
for ( char valueofChar : arrayOfCharacters ) {
System.out.println( valueofChar );
}
}
}
Output of above code:
C o d e B l o g M o n e y
