在Java中分隔十进制值

String decimalValue = "123,456,789";
String[] parts = decimalValue.split(",");
for (String part : parts) {
    System.out.println(part);
}

123
456
789

String decimalValue = "123, 456, 789";
String[] parts = decimalValue.split("[,\\s]+");
for (String part : parts) {
    System.out.println(part);
}

123
456
789

String decimalValue = "123, 456, 789";
Scanner scanner = new Scanner(decimalValue);
scanner.useDelimiter("[,\\s]+");
while (scanner.hasNext()) {
    System.out.println(scanner.next());
}
scanner.close();
