Java Bidi getLevelAt()方法及实例

java.text.Bidi 类的 getLevelAt() 方法是用来提供bidi文本行中特定点上的特定字符的解析水平。

语法

public int getLevelAt(int offset)

参数：该方法获取需要解决的级别的文本行中存在的字符的偏移量。
返回值： 该方法为偏移量作为参数的特定字符提供解决的级别，如果偏移量小于零或大于整个bidi文本的长度，那么它只是返回相等的基本级别。下面是说明 getLevelAt() 方法的例子：

例1 :

// Java program to demonstrate// getLevelAt() method import java.text.*;import java.util.*;import java.io.*; public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi = new Bidi("Geeks for Geeks", 0);         int offset = 3;         // getting resolved level of Character        // using getLevelAt() method        int status = bidi.getLevelAt(offset);         // display the result        if (offset > 0            && (bidi.getLength()) > offset)            System.out.println(                "resolved level of the "                + "Character at offset "                + offset + " is "                + status);        else            System.out.println(                "base direction level is "                + status);    }}

输出

resolved level of the Character at offset 3 is 0

例2 :

// Java program to demonstrate// getLevelAt() method import java.text.*;import java.util.*;import java.io.*; public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi = new Bidi("Tajmahal", 0);         int offset = -3;         // getting resolved level of Character        // using getLevelAt() method        int status = bidi.getLevelAt(offset);         // display the result        if (offset > 0            && (bidi.getLength()) > offset)            System.out.println(                "resolved level of the "                + "Character at offset "                + offset + " is "                + status);        else            System.out.println(                "base direction level is "                + status);    }}

输出
