condition are:false condition are:false condition are:true string array are==>amma string array are==>senthil string array are==>kumar string array are==>amma condition are:false condition are:false string array are==>amma string array are==>senthil string array are==>kumar string array are==>amma condition are:false string array are==>amma string array are==>senthil string array are==>kumar string array are==>amma string array are==>amma string array are==>senthil string array are==>kumar string array are==>amma 

but excepting output string array are===>{"amma","senthil","kumar"};

could 1 can guide on please????

please change if(arr[i]==arr[j]) if(arr[i].equals(arr[j]))

while comparing string objects should use equals() method instead of "=="
