SimpleTimeZone類的equals()方法 (SimpleTimeZone 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 SimpleTimeZone and the given object (ob) are equals or not.

  equals()方法用于檢查此SimpleTimeZone與給定的對象(ob)是否相等。

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

  equals()方法是一種非靜態方法，可通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

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

  在檢查兩個對象的相等性時， equals()方法不會引發異常。

Syntax:

句法：

    public boolean equals(Object ob);

Parameter(s):

參數：

• Object ob – represents the object to check with this object for equality.

  對象ob –表示要與此對象檢查是否相等的對象。

Return value:

返回值：

The return type of the method is boolean, it returns true when both the objects are equal otherwise it returns false.

該方法的返回類型為boolean ，當兩個對象相等時返回true，否則返回false。

Example:

例：

// Java program to demonstrate the example 
// of boolean equals(Object ob) method of 
// SimpleTimeZone
import java.util.*;
public class EqualsOfSimpleTimeZone {
public static void main(String args[]) {
// Instantiate SimpleTimeZone object
TimeZone s_tz = SimpleTimeZone.getDefault();
System.out.println("s_tz: " + s_tz);
// By using clone() method is to
// return shallow copy of this
// simpletimezone s_tz
Object stz_clone = s_tz.clone();
System.out.println("s_tz.clone(): " + stz_clone);
// By using equals() method is to
// check the equality of two SimpleTimeZone
// objects
boolean status = s_tz.equals(stz_clone);
System.out.println("s_tz.equals(stz_clone): " + status);
}
}

Output

輸出量

s_tz: sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
s_tz.clone(): sun.util.calendar.ZoneInfo[id="GMT",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
s_tz.equals(stz_clone): true
