Answer 1

Moses Solomon Ayofemi

The } before int t = arr.length is causing your first problem.

Delete it from that position and place it with the other 2 at the base of code
}
}
}

Then you will be able to access your for loop, which is creating an index error

Adjust t-1

You might also wish to adjust your print statement

for(int r = t-1; r >= 0; r-- ){
System.out.print( arr[r]) ;

Answer 2

You accidentally deleted a closing }

Plus, I think it should be
int t=arr.length-1;
as indexing starts from 0 and length != last index

Answer 3

//} deleted
int t=arr.length-1;
for (int r = t; r >= 0; r-- ) {
System.out.println( arr[r]) ;
} //added
}
}
