64-bit os means
CPU register is 64 bit
It stores information in hard disk as 64-bit format
Data in main memory stored in 64-bit
OS is developed using 64-bit compiler
Given: 1. public class Person { 2. private String name; 3. public Person(String name) { this.name = name; } 4. public boolean equals(Person p) { 5. return p.name.equals(this.name); 6. } 7. } Which statement is true?
The equals method does NOT properly override the Object.equals method.
Compilation fails because the private attribute p.name cannot be accessed in line 5.
To work correctly with hash-based data structures, this class must also implement the hashCode method.
When adding Person objects to a java.util.Set collection, the equals method in line 4 will prevent duplicates.
