原文:https://www . geesforgeks . org/field position-getendindex-method-in-Java-with-example/

java.text.FieldPosition 类的 getEndIndex() 方法用于获取 FieldPosition 对象中最后一个字符前面的字符的索引。

语法:

public int getEndIndex()

参数:该方法不接受任何参数作为参数。

返回值:该方法返回 FieldPosition 对象中最后一个字符前面的字符的索引

以下是说明 getEndIndex() 方法的示例:

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

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
