Program Java untuk Mengulangi setiap watak rentetan.

Dalam tutorial ini, kita akan belajar mengulangi setiap watak rentetan.

Untuk memahami contoh ini, anda harus mempunyai pengetahuan mengenai topik pengaturcaraan Java berikut:

  • Rentetan Java
  • Java untuk Gelung
  • Java untuk-setiap Gelung

Contoh 1: Gelung setiap watak rentetan menggunakan gelung

 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.
