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.
