Java中的 Bidi getRunStart() 方法和示例
Java.text.Bidi类的getRunStart()方法用于提供此 Bidi 实例第 n 次运行开始的第一个字符的索引。
句法:
public int getRunStart(int run)
参数:此方法接受要为其检索运行开始的逻辑运行的索引。
返回值:此方法提供第 n 次逻辑运行的起始字符索引。
以下是说明getRunStart()方法的示例:
示例 1:
// Java program to demonstrate
// getRunStart() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing Bidi
// with base direction
Bidi bidi = new Bidi("Tajmahal", 0);
int index = 0;
// getting the start of run for the index 0
// using getRunStart() method
int level = bidi.getRunStart(index);
// display the result
System.out.println(
"start of run for index 0 is : "
+ level);
}
}
输出:
start of run for index 0 is : 0
示例 2:
// Java program to demonstrate
// getRunStart() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing Bidi
// with base direction
Bidi bidi
= new Bidi("Geeks for Geeks", 1);
int index = 0;
// getting the start of run for the index 0
// using getRunStart() method
int level = bidi.getRunStart(index);
// display the result
System.out.println(
"start of run for index 0 is : "
+ level);
}
}
输出:
start of run for index 0 is : 0
