My log messages is printing only 2 times in Android

Question

Why in this loop "hello world" is shown just 2 times, not 20 times?

 for(int j=0; j<20; j++){
   Log.d("myTag","hello world");
 }

Please explain what's going on.

You are logging same tag and value each time , Just try `Log.d("myTag"+j,"hello world"+jj)`. — ADM, May 04 '20 at 16:10

Maybe this is because of identical tag names or messages. Seems that it doesn't allow more than two same logs. You can use

for(int j=0;j<20;j++){
    Log.d("myTag" + j,"hello world");
 }

or

for(int j=0;j<20;j++){
    Log.d("myTag","hello world" + j);
}

In logcat you can see these lines,

Also you have the same issue with this loop:

for (j in 0..19) {
            Log.d("myTag", "${j/20}")
        }

But this loop runs as desired:

for (j in 0..19) {
            Log.d("myTag", "$j")
        }
