编程：编写一个截取字符串的函数，输入为一个字符串和字节数，输出为按字节截取的字符串。...

import java.util.Scanner; class SplitString { String SplitStr; int SplitByte; public SplitString(String str, int bytes) { SplitStr = str; SplitByte = bytes; } public void SplitIt() { int loopCount = SplitStr.length() % SplitByte == 0 ? SplitStr.length() / SplitByte : SplitStr.length() / SplitByte + 1; for (int i = 1; i <= loopCount; i++) { System.out.println(i == loopCount ? SplitStr.substring((i - 1) * SplitByte, SplitStr.length()) : SplitStr.substring( (i - 1) * SplitByte, (i * SplitByte))); } } public static void main(String[] args) { System.out.println("输入为一个字符串和字节数，输出为按字节截取的字符串"); Scanner scanner = new Scanner(System.in); SplitString ss = new SplitString(scanner.next(), scanner.nextInt()); ss.SplitIt(); } }
