Java program a karakterlánc egyes karakterein keresztül.

Ebben az oktatóanyagban megtanuljuk megismételni a karakterlánc egyes karaktereit.

A példa megértéséhez ismernie kell a következő Java programozási témákat:

  • Java karakterlánc
  • Java a hurokhoz
  • Java minden hurokhoz

1. példa: Keresse meg a karakterlánc egyes karaktereit a ciklus használatával

 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.
