== used for comparing two Strings Objects rather than value. 
 
.equels is used for comparing two strings

== is equals is used for checking the equality of values of all datatypes, 
.equals is used for checking the equaliy of strings.

== is used to check whether the references of the both are equal or not?

.equals() is used to the compare the values in that references.

== is used to compare the number type data types viz. int, float,double  and also the boolean datatypes.

e.g. int x=10;

if(x==10)

{

// your code

}

boolean flag = true;

if(flag==false)

{

// Action1

}

if(flag==ture)

{

//Action2

}

.equals() method is used to compare the String data types

viz.

String str = "Hello";

if(str.equals("Hello"))

{

// Your code of action

}

1.    == is swallo comparison. Means it will use the memory location for comparison rather that the data.

2. .equals() is indepth comparison. I will check the content between two object rather that the memory location.

== is used for checking the datatypes values like int,float,double..

.equals is used to check the Objects like String,Vector ....

The difference between ==  and .equals is

String a="john",b="joi";

if (a.equals(b))// it compares internaly for the same materials

if(a==b)// it compares for the memory location

.equals -> Compares chracters between two strings are equal.
==        -> Compares  object reference between two strings are same .

In case of .equals,the contents of the objects are compared.
in case of ==,the data types of objects are compared.

== is used to compare the values of primitive typed variables and the memory location of Objects.
equals is used to compare the content of the two objects.

== is normally much faster than equals since it just checks the memory location of two objects.

The difference can be told in this simple way, for any object:

obj.clone() == obj
will always be wrong while

obj.clone().equals(obj)
will always be right.

equals() to method is used to compares only the values in a  String .
While == operator is used to compare values as well as hashcode or memory allocation. This is used to compare to objects

== is used to check whether the two objects are referes to the same object
.equals() methos is used to check whether the two objects are meaning fully equal

In Java == is used to check the referance of  variables
but . equals is used to check the value.

CASE1:

       String s3 = "hi";
        String s="hi";
        String s2=s3;
       
        System.out.println("hash code S " +s.hashCode());
        System.out.println("hash code S2 " +s2.hashCode());
        System.out.println("hash code S3 " +s3.hashCode());
        System.out.println("double equal "+(s==s2));
        System.out.println("equal "+ s.equals(s2));

out put:
double equal true
equal true

JVM crate only one Object and pointing to three reffernce variable.
Since   refferences are pointing to same object propertie i.e s,s3,s2 pointing to "hi' .so == ill compare the refferences  locations,so here refferences locations are same ,so ill get true.
.equals compare the object properties ,here object properties same ,ill get true .

CASE 2:

     String s1 = new String("hi");
        String s2 ="hi";
        System.out.println("double equal " +(s1==s2));
        System.out.println("equal  " +s1.equals(s2));

out put is :

double equal false
equal  true

so == comapre the reffernces but .equals compare the object properties.

Thanks,
Malli.

The == operator compares the reference of an abject passed where as the .equals function compares the two string passed to it.

== is just a comparison operator of comparing two integer type.
& is a comparison operator for binary .
.equal(String s) is a String comparison method for comparing two strings.

Equals() method is expected to check for the equivalence the contents of the objects.

Whereas the == operator is expected to check the actual object instances are same or not.

Code
s1 = new String("abc");


 s2 = new String("abc");


 


if(s1.equals(s2))


      System.out.println("s1.equals(s2) is TRUE");


 else


      System.out.println("s1.equals(s2) is FALSE");

The "==" operator can be used to test primitive values for equality, and can also be used to determine if two object references point to the same underlying object.

For Java objects, the equals method will return true if the argument is equal to the object on which the method is invoked, where equality is defined by the objects class implementation of the equals method.
