PropertyPermission類equals()方法 (PropertyPermission Class equals() method)

• equals() method is available in java.util package.

  equals()方法在java.util包中可用。

• equals() method is used to check whether this object and the given object (ob) are equal or not.

  equals()方法用于檢查此對象與給定對象(ob)是否相等。

• equals() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  equals()方法是一種非靜態(tài)方法，僅可通過類對象訪問，如果嘗試使用類名訪問該方法，則會(huì)收到錯(cuò)誤消息。

• equals() method does not throw an exception at the time of checking the equality of two objects.

  在檢查兩個(gè)對象的相等性時(shí)， equals()方法不會(huì)引發(fā)異常。

Syntax:

句法：

public boolean equals(Object ob);

Parameter(s):

參數(shù)：

• Object ob – represents the object to be tested with this object in this PropertyPermission.

  對象ob –表示要在此PropertyPermission中與此對象一起測試的對象。

Return value:

返回值：

The return type of the method is boolean, it returns true when both the object are same, equals otherwise it returns false.

該方法的返回類型為boolean ，當(dāng)兩個(gè)對象相同時(shí)返回true ，否則返回false 。

Example:

例：

// Java program to demonstrate the example // of boolean equals(Object ob) method of // PropertyPermissionimport java.util.*;public class EqualsOfPropertyPermission {public static void main(String arg[]) {// Instantiates two PropertyPermission objectPropertyPermission prop_perm1 = new PropertyPermission("os.version", "write");PropertyPermission prop_perm2 = new PropertyPermission("os.name", "read");// By using equals() method is to// whether two PropertyPermission// objects are same or not in terms// of name and actionsboolean status = prop_perm1.equals(prop_perm2);System.out.print("prop_perm1.equals(prop_perm2): ");System.out.println(status);} }

Output

輸出量

prop_perm1.equals(prop_perm2): false
