Java 中的 BreakIterator next()方法，示例
原文:https://www . geeksforgeeks . org/breakiterator-next-method-in-Java-with-examples/
java.text.BreakIterator 类的 next() 方法用于获取当前边界(通过调用 current()方法检索的边界)之前的下一个边界的索引。它提供边界的第一个字符的偏移量，该偏移量跟随 BreakIterator 指向的当前边界。
语法:
public abstract int next()
参数:此方法不接受任何参数。
返回值:该方法提供当前边界之后的下一个边界的索引。
以下是说明 next() 方法的示例:
例 1:
// Java program to demonstrate next() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing with zero
int current = 0, next = 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
next = wb.next();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 1st next() : "
+ next);
// calling next method
next = wb.next();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 2nd next() : "
+ next);
}
}
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 next() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing with zero
int current = 0, next = 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
next = wb.next();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 1st next() : "
+ next);
// calling next method
next = wb.next();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 2nd next() : "
+ next);
}
}
输出:
current position before calling next() : 0
current position after calling 1st next() : 13
current position after calling 2nd next() : -1
