下面是一些例子来说明 baseIsLeftToRight() 方法。
例子 1 :
// Java program to demonstrate
// baseIsLeftToRight() 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",
Bidi.DIRECTION_LEFT_TO_RIGHT);
// checking base direction
// using baseIsLeftToRight() method
boolean status
= bidi.baseIsLeftToRight();
// display the result
if (status)
System.out.println(
"Base direction is "
+ "left to right");
else
System.out.println(
"Base direction is "
+ "right to left");
}
}
输出
Base direction is left to right
例2 :
// Java program to demonstrate
// baseIsLeftToRight() 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",
Bidi.DIRECTION_RIGHT_TO_LEFT);
// checking base direction
// using baseIsLeftToRight() method
boolean status
= bidi.baseIsLeftToRight();
// display the result
if (status)
System.out.println(
"Base direction is "
+ "left to right");
else
System.out.println(
"Base direction is "
+ "right to left");
}
}
输出
Base direction is right to left
