Java 中的 Bidi getLevelAt()方法，带示例

原文:https://www . geesforgeks . org/bidi-getlevelat-method-in-Java-with-examples/

类的 getLevelAt() 方法用于提供出现在 Bidi 文本行上特定点的特定字符的解析级别。

语法:

public int getLevelAt(int offset)

参数:该方法取需要解析级别的文本行中当前字符的偏移量。

返回值:如果偏移量小于零或大于 bidi 文本的整个长度，则该方法为特定字符提供解析级别，该字符的偏移量作为参数给出，而不仅仅返回等效的基本级别。

以下是说明 getLevelAt() 方法的示例:

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:

base direction level is 0
