Java 中的 CompositeName compareTo()方法，带示例
原文:https://www . geesforgeks . org/composite name-compare to-method-in-Java-with-examples/
javax.naming.CompositeName 类的 compareTo() 方法用于将该 CompositeName 与作为参数传递的指定对象进行比较。它返回一个负整数、零或正整数，因为该组合名称小于、等于或大于给定的对象作为参数。如果传递的对象为空或者不是 CompositeName 的实例，则该方法将引发 ClassCastException。
语法:
public int compareTo(Object obj)
参数:该方法接受对象，该对象是非空对象进行比较。
返回值:此方法返回一个负整数、零或正整数，因为此名称小于、等于或大于给定的对象。
异常: 如果 obj 不是 CompositeName，这个方法抛出 ClassCastException。
下面的程序说明了 CompositeName.compareTo()方法: 程序 1:
// Java program to demonstrate
// CompositeName.compareTo()
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
// create Composite name object
CompositeName compositeName1
= new CompositeName("x/y");
CompositeName compositeName2
= new CompositeName("x/z");
// apply compareTo()
int value
= compositeName1.compareTo(compositeName2);
// print value
if (value > 0)
System.out.println("CompositeName1 is "
+ "greater than CompositeName2");
else if (value < 0)
System.out.println("CompositeName1 is "
+ "smaller than CompositeName2");
else
System.out.println("CompositeName1 is "
+ " equal to CompositeName2");
}
}
Output:
CompositeName1 is smaller than CompositeName2
程序 2:
// Java program to demonstrate
// CompositeName.compareTo() method
import javax.naming.CompositeName;
import javax.naming.InvalidNameException;
public class GFG {
public static void main(String[] args)
throws InvalidNameException
{
// create Composite name object
CompositeName compositeName1
= new CompositeName("x/y/z/a");
CompositeName compositeName2
= new CompositeName("x/y/x/a");
// apply compareTo()
int value
= compositeName1.compareTo(compositeName2);
// print value
if (value > 0)
System.out.println("CompositeName1 is "
+ "greater than CompositeName2");
else if (value < 0)
System.out.println("CompositeName1 is "
+ "smaller than CompositeName2");
else
System.out.println("CompositeName1 is "
+ " equal to CompositeName2");
}
}
Output:
CompositeName1 is greater than CompositeName2
