El método anterior() de la clase java.text.BreakIterator se usa para obtener el índice del límite anterior detrás del límite actual (límite recuperado llamando al método actual()). Proporciona el desplazamiento del primer carácter del límite que precede al límite actual señalado por BreakIterator.
Sintaxis:
public abstract int previous()
Parámetro: Este método no acepta ningún parámetro.
Valor de retorno: este método proporciona el índice del límite anterior que sigue al límite actual.
A continuación se muestran los ejemplos para ilustrar el método anterior() :
Ejemplo 1:
// Java program to demonstrate previous() 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");
// setting the current position to index 11
// By skipping 3 boundaries
wb.next(3);
// getting the current text boundary
current = wb.current();
// display the result
System.out.println(
"current position before"
+ " calling previous() : "
+ current);
// calling previous() method
next = wb.previous();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 1st previous() : "
+ next);
// calling previous() method
next = wb.previous();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 2nd previous() : "
+ next);
}
}
current position before calling previous() : 11 current position after calling 1st previous() : 6 current position after calling 2nd previous() : 4
Ejemplo 2:
// Java program to demonstrate
// previous() 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");
// setting the current position to index 11
// By skipping 3 boundaries
wb.next(3);
// getting the current text boundary
current = wb.current();
// display the result
System.out.println(
"current position before"
+ " calling previous() : "
+ current);
// calling previous() method
next = wb.previous();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 1st previous() : "
+ next);
// calling previous() method
next = wb.previous();
// display the result
System.out.println(
"\ncurrent position after"
+ " calling 2nd previous() : "
+ next);
}
}
current position before calling previous() : 13 current position after calling 1st previous() : 0 current position after calling 2nd previous() : -1
