• 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.

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 // SimpleTimeZoneimport java.util.*;public class EqualsOfSimpleTimeZone {public static void main(String args[]) {// Instantiate SimpleTimeZone objectTimeZone s_tz = SimpleTimeZone.getDefault();System.out.println("s_tz: " + s_tz);// By using clone() method is to// return shallow copy of this// simpletimezone s_tzObject 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// objectsboolean 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
