Programa Java para iterar cada caractere da string.

Neste tutorial, aprenderemos a iterar em cada caractere da string.

Para entender este exemplo, você deve ter conhecimento dos seguintes tópicos de programação Java:

  • Java String
  • Java para Loop
  • Java para cada Loop

Exemplo 1: Loop através de cada caractere de uma string usando loop for

 class Main ( public static void main(String() args) ( // create a string String name = "Programiz"; System.out.println("Characters in " + name + " are:"); // loop through each element for(int i = 0; i

Output

 Characters in Programiz are: P, r, o, g, r, a, m, i, z,

In the above example, we have used the for-loop to access each element of the string. Here, we have used the charAt() method to access each character of the string.

Example 2: Loop through each character of a string using for-each loop

 class Main ( public static void main(String() args) ( // create a string String name = "Programiz"; System.out.println("Characters in string "" + name + " ":"); // loop through each element using for-each loop for(char c : name.toCharArray()) ( // access each character System.out.print(c + ", "); ) ) )

Output

 Characters in string "Programiz": P, r, o, g, r, a, m, i, z,

In the above example, we have converted the string into a char array using the toCharArray(). We then access each element of the char array using the for-each loop.
