Java中的 FieldPosition getEndIndex() 方法与示例

Java .text.FieldPosition类的getEndIndex()方法用于获取FieldPosition 对象中最后一个字符之前的字符的索引。

句法:

public int getEndIndex()

参数:此方法不接受任何参数作为参数。

返回值:此方法返回 FieldPosition 对象中最后一个字符之前的字符的索引

以下是说明getEndIndex()方法的示例:

示例 1:

// Java program to demonstrate
// getEndIndex() method
  
import java.text.*;
import java.util.*;
import java.io.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
  
            // Creating and initializing
            // new FieldPosition Object
            FieldPosition pos
                = new FieldPosition(
                    DateFormat.Field.AM_PM);
  
            // getting end index of FieldPosition Object
            // using getEndIndex() method
            int i = pos.getEndIndex();
  
            // display result
            System.out.println("end index :- " + i);
        }
  
        catch (ClassCastException e) {
  
            System.out.println("Exception thrown : " + e);
        }
    }
}
输出:
end index :- 0

示例 2:

// Java program to demonstrate
// getEndIndex() method
  
import java.text.*;
import java.util.*;
import java.io.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
  
            // Creating and initializing
            // new FieldPosition Object
            FieldPosition pos
                = new FieldPosition(
                    DateFormat.Field.AM_PM);
  
            // setting end index
            pos.setEndIndex(5);
  
            // getting end index of FieldPosition Object
            // using getEndIndex() method
            int i = pos.getEndIndex();
  
            // display result
            System.out.println("end index :- " + i);
        }
  
        catch (ClassCastException e) {
  
            System.out.println("Exception thrown : " + e);
        }
    }
}
输出:
end index :- 5
