用java代码些顺序串的基本运算算法

你好,关于你的问题,我可以回答如下:
对于顺序串的基本运算算法,可以参考以下Java代码实现:
```java
public class SeqString {
private final int MAXSIZE = 1000; // 存储容量
private char[] data; // 存储顺序串的字符数组
private int length; // 存储顺序串的长度
// 构造函数1:传入一个字符串
public SeqString(String str) {
length = str.length();
if (length > MAXSIZE) {
throw new RuntimeException("超出存储容量");
}
data = str.toCharArray();
}
// 构造函数2:传入一个字符数组
public SeqString(char[] arr) {
length = arr.length;
if (length > MAXSIZE) {
throw new RuntimeException("超出存储容量");
}
data = arr.clone();
}
// 拼接顺序串
public SeqString concat(SeqString str) {
char[] newData = new char[length + str.length];
System.arraycopy(data, 0, newData, 0, length);
System.arraycopy(str.data, 0, newData, length, str.length);
return new SeqString(newData);
}
// 截取顺序串
public SeqString substring(int beginIndex, int endIndex) {
if (beginIndex < 0 || endIndex > length || beginIndex >= endIndex) {
throw new IndexOutOfBoundsException();
}
char[] newData = new char[endIndex - beginIndex];
System.arraycopy(data, beginIndex, newData, 0, endIndex - beginIndex);
return new SeqString(newData);
}
// 判断是否相等
public boolean equals(SeqString str) {
if (length != str.length) {
return false;
}
for (int i = 0; i < length; i++) {
if (data[i] != str.data[i]) {
return false;
}
}
return true;
}
}
```
以上代码实现了顺序串的拼接、截取和比较操作。需要注意的是,在实际开发中,为了提高效率,可以通过维护一个字符数组的“长度”属性来节约空间。还有就是,为了方便处理中文字符等多字节字符,可以采用Unicode编码。
