Last Updated :

The previous() method of java.text.BreakIterator class is used to get the index of the previous boundary behind the current boundary(boundary retrieved by calling current() method). It provides the offset of the first character of boundary which precedes the current boundary pointed by BreakIterator.
Syntax:
public abstract int previous()
Parameter: This method does not accept any parameter.
Return Value: This method provides the index of the previous boundary following the current boundary.
Below are the examples to illustrate the previous() method:
Example 1:
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
int current = 0 , next = 0 ;
BreakIterator wb
= BreakIterator.getWordInstance();
wb.setText( "Code Geeks" );
wb.next( 3 );
current = wb.current();
System.out.println(
"current position before"
+ " calling previous() : "
+ current);
next = wb.previous();
System.out.println(
"\ncurrent position after"
+ " calling 1st previous() : "
+ next);
next = wb.previous();
System.out.println(
"\ncurrent position after"
+ " calling 2nd previous() : "
+ next);
}
}
|
Output:
current position before calling previous() : 11
current position after calling 1st previous() : 6
current position after calling 2nd previous() : 4
Example 2:
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
int current = 0 , next = 0 ;
BreakIterator wb
= BreakIterator.getWordInstance();
wb.setText( "GeeksForGeeks" );
wb.next( 3 );
current = wb.current();
System.out.println(
"current position before"
+ " calling previous() : "
+ current);
next = wb.previous();
System.out.println(
"\ncurrent position after"
+ " calling 1st previous() : "
+ next);
next = wb.previous();
System.out.println(
"\ncurrent position after"
+ " calling 2nd previous() : "
+ next);
}
}

Output:
current position before calling previous() : 13
current position after calling 1st previous() : 0
current position after calling 2nd previous() : -1
