Java Data Type - 如何将字符串拆分成子字符串

Use the split() method to split a string into multiple strings. 



Splitting is performed using a delimiter.



The split() method returns an array of String. 


public class Main {
  public static void main(String[] args) {
    String str = "A,B,C,D";

    // Split str using a comma as the delimiter
    String[] parts = str.split(",");

    // Print the the string and its parts
    System.out.println(str);

    for (String part : parts) {
      System.out.println(part);
    }
  }
}
