参数:该方法不接受任何参数作为参数。 返回值:该方法返回基于规则的排序器对象初始化时使用的规则。
以下是说明 getRules() 方法的示例:
例 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// getRules() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing new simple rule
String simple = "< a < c & a < b";
// Creating and initializing
// new RuleBasedCollator Object
RuleBasedCollator col
= new RuleBasedCollator(simple);
// getting rule of this object
// using getRules() method
String rule = col.getRules();
// display result
System.out.println("rule is :- "
+ rule);
}
catch (ClassCastException e) {
System.out.println("Exception thrown : "
+ e);
}
catch (ParseException e) {
System.out.println("Exception thrown : "
+ e);
}
}
}
Output:
rule is :- < a < c & a < b
例 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to demonstrate
// getRules() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing new simple rule
String simple = "< a < b < c < d";
// Creating and initializing
// new RuleBasedCollator Object
RuleBasedCollator col
= new RuleBasedCollator(simple);
// getting rule of this object
// using getRules() method
String rule = col.getRules();
// display result
System.out.println("rule is :- "
+ rule);
}
catch (ClassCastException e) {
System.out.println("Exception thrown : "
+ e);
}
catch (ParseException e) {
System.out.println("Exception thrown : "
+ e);
}
}
}
Output:
rule is :- < a < b < c < d
