参数：此方法不接受任何参数作为参数。

返回值：此方法返回在基于规则的整理器对象初始化期间使用的规则。

下面是说明getRules()方法的示例：

范例1：

// 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 initalizing 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() mehtod 
            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); 
        } 
    } 
}

输出：

rule is:- < a < c & a < b

范例2：

// 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 initalizing 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() mehtod 
            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); 
        } 
    } 
}

输出：

rule is:- < a < b < c < d
