first of all that s1=s2; s1==s2 seond one is if u consider s1==s2; s2==s3; s3==s4; s4==s1; when s1==s2--output abc when s2==s3---output is not abc coz both string define in diff methods when s3==s4---output abc when s4==s1----output is not abc coz both string define in diff methods

Run it. Nothing. You are assigning variables, and you have no output. equals checks that the content is "identical". == checks that the two refrences point to the same object.

for the above programme if u print the values if s1,s2,s3,s4 the output is nothing more than "abc" but if you compare like this s1==s2;s2==s3;s3==s4;s4==s1; n print the values of s1,s2,s3,s4 this will cause in 4 errors i.e "s1==s2 is not a statement" 4 errors like this..
