Java中的 Bidi getRunLevel() 方法及示例
Java.text.Bidi类的getRunLevel()方法用于为这行文本的第 n 次运行提供级别,如果只有一个运行状态,它将为该状态提供基本级别。
句法:
public int getRunLevel(int run)
参数:此方法接受要为其检索运行级别的逻辑运行的索引。
返回值:此方法提供文本行中特定运行的级别。
下面是说明getRunLevel()方法的示例:
示例 1:
// Java program to demonstrate
// getRunLevel() 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",
Bidi.DIRECTION_RIGHT_TO_LEFT);
// index for which level is needed
int index = 0;
// getting the level of run
// using getRunLevel() method
int level = bidi.getRunLevel(index);
// display the result
System.out.println(
"level of first run is : "
+ level);
}
}
输出:
level of first run is : 2
示例 2:
// Java program to demonstrate
// getRunLevel() 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",
Bidi.DIRECTION_LEFT_TO_RIGHT);
// index for which level is needed
int index = 0;
// getting the level of run
// using getRunLevel() method
int level = bidi.getRunLevel(index);
// display the result
System.out.println(
"level of first run is : "
+ level);
}
}
输出:
level of first run is : 0
