== and .equals() not working in java [duplicate]

So I was trying to compare the string in PackageInfo and ApplicationInfo and retrieve their package name in Android Studio.

    List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
    List<PackageInfo> apps = pm.getInstalledPackages(PackageManager.GET_PERMISSIONS);

            for (PackageInfo app : apps)
                for(ApplicationInfo packageInfo:packages)
                        String packageName = packageInfo.packageName;
                        String sysName = app.packageName;

                        if (packageName != sysName)
                        {
                            Log.d("", "NOPE DOESNT MATCH");
                            break;
                        }
                        if (packageName.equals(sysName.toString())) ;
                        {
                            Log.d("", "IT MATCHES");
                        //do something after that

So the problem came by when I saw inside the debug mode, they actually HAD the same string

Example in debug mode :

com.android.quicksearchbox

com.android.quicksearchbox

It returns as "NOPE DOESNT MATCH"

I'm really curious why this will happen and I have tried other form like trim to take off away white spaces between and no, it still does not return me "IT MATCHES", can anyone help please?

Thanks.

Replace: if (packageName != sysName)

With: if (!packageName.equals(sysName.toString()))

Also, you have a ; at the end of if which shouldn't be there. (Here: if (packageName.equals(sysName.toString())) ;)

Actually, to form your condition better, you should have an if-else block instead of 2 ifs.

something like:

if (packageName.equals(sysName.toString())){
    Log.d("", "IT MATCHES");
} else {
    Log.d("", "NOPE DOESNT MATCH");
}
