String - Java

Answer 1

String str = "hello";

String
str1 = "abcd",

System.out.println( System.identityHashCode(str1) );
System.out.println( System.identityHashCode(str2) );

Answer 3

Hashcode is a unique code or an 32bit integer number generated by the JVM at time of object creation in java.
https://www.geeksforgeeks.org/method-class-hashcode-method-in-java/

public static int identityHashCode(Object x)

Returns the same hash code for the given object as would be returned by the default method hashCode(), whether or not the given object's class overrides hashCode(). The hash code for the null reference is zero.

https://docs.oracle.com/javase/8/docs/api/java/lang/System.html#identityHashCode-java.lang.Object-

public class Program
{
public static void main(String[] args) {
String
str1 = "abcd",
str2 = "abcd";
System.out.println(System.identityHashCode(str1) );
System.out.println(System.identityHashCode(str2));
System.out.println( str1.hashCode() ); //32bit
System.out.println( str2.hashCode() );
}
}
