Java 中 BreakIterator current()方法，示例

原文:https://www . geesforgeks . org/breakiterator-current-method-in-Java-with-examples/

java.text.BreakIterator 类的 current() 方法用于获取该行单词中最近文本边界的索引。它提供当前由 BreakIterator 指向的文本的偏移量。

语法:

public abstract int current()

参数:此方法不接受任何参数。

返回值:该方法提供最近文本边界的索引。

以下是说明电流()方法的例子:

例 1:

// Java program to demonstrate current() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing integer with zero
        int current = 0, last = 0;

        // creating and initializing BreakIterator
        BreakIterator wb
            = BreakIterator.getWordInstance();

        // setting text for BreakIterator
        wb.setText("Code  Geeks");

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "current position "
            + "before calling next(): "
            + current);

        // calling next method
        last = wb.next();

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 1st next(): "
            + current);

        // calling next method
        last = wb.next();

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 2nd next(): "
            + current);
    }
}

输出:

current position before calling next(): 0

current position after calling 1st next(): 4

current position after calling 2nd next(): 6

例 2:

// Java program to demonstrate current() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing integer with zero
        int current = 0, last = 0;

        // creating and initializing BreakIterator
        BreakIterator wb
            = BreakIterator.getWordInstance();

        // setting text for BreakIterator
        wb.setText("GeeksForGeeks");

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "current position "
            + "before calling next(): "
            + current);

        // calling next method
        last = wb.next();

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 1st next(): "
            + current);

        // calling next method
        last = wb.next();

        // getting the current text boundary
        current = wb.current();

        // display the result
        System.out.println(
            "\ncurrent position after"
            + " calling 2nd next(): "
            + current);
    }
}

输出:

current position before calling next(): 0

current position after calling 1st next(): 13

current position after calling 2nd next(): 13
