Java中java.text.CharacterIterator接口的previous()方法用於獲取此CharacterIterator讀取的先前字符。此方法將該迭代器遞減為一個索引,然後返回該前一個字符。
用法:
public char previous()
參數:此方法不接受任何參數。
返回值:此方法返回此CharacterIterator讀取的前一個字符。
異常:此方法不引發任何異常。
程序:
// Java program to demonstrate
// the above method
import java.text.*;
import java.util.*;
public class CharacterIteratorDemo {
public static void main(String[] args)
{
CharacterIterator characterIterator
= new StringCharacterIterator(
"GeeksForGeeks");
characterIterator.next();
System.out.println("Current character: "
+ characterIterator
.current());
System.out.println("Previous character: "
+ characterIterator
.previous());
}
}
輸出:
Current character: e Previous character: G
