Java program iterates over each character in the string

Comprehensive Java Examples

In this tutorial, we will learn to traverse each character of the string.

To understand this example, you should understand the followingJava programmingTopic:

• Java string

• Java for Loops

• Java for-each loop

Example1Use for loop to traverse each character of the string

class Main {
　　public static void main(String[] args) {
　　　　//Create a string
　　　　String name = "w3codebox";
　　　　System.out.println( name　+　"The characters in ");
　　　　//Loop through each element
　　　　for(int i = 0; i<name.length(); i++) {
　　　　　　//Access each character
　　　　　　char a = name.charAt(i);
　　　　　　System.out.print(a　+　"', ");
　　　　}
　　}
}

Output Result

w3The characters in codebox are:
n,h,o,o,o,

In the above example, we usedfor loopto access each element of the string. Here, we use the charAt() method to access each character of the string.

Example2：Use for-each loop traverses each character of the string

class Main {
　　public static void main(String[] args) {
　　　　//Create a string
　　　　String name = "w3codebox";
　　　　System.out.println( name　+　"The characters in ");
　　　　//Use for-each loop traverses each element
　　　　for(char c : name.toCharArray()) {
　　　　　　//Access each character
　　　　　　System.out.print(c　+　"', ");
　　　　}
　　}
}

Output Result

w3The characters in codebox are:
n,h,o,o,o,

In the above example, we use toCharArray() to convert the string to a char array. Then, we use for-each loop Access each element of the char array.
