Consider the following code segment.

St r ing$[][]$ let ters $=\{\{"$A$","$B$","$C$","$D$"\},$

$\{"$E$","$F$","$G$","$H$"\},$

$\{"$I$","$J$","$K$","$L$"\}\}$;

for $($ int col $=1$; col $<$ let ters$[0].$ length; col$++)$

$\{$

for $($ int row $=1$; row $<$ let ters. length; row$++)$

$\{$

System.out $.$pr int $($ let ters$[$row$][$col $]+"")$ ;

$\}$

System.out $.$pr int ln$()$ ;

$\}$

What is printed as a result of executing this code segment?
