You worked late into the night on an assignment and didn't realize that you wrote a huge section of your term paper with your ¯ngers on the wrong home keys!

Question

Where you mean to type: \This is an unruly mob." You actually typed: \Ty8s
8s ah 7hr7o6 j9b."
Basically you swapped: 7 for U, 8 for I, 9 for O, 0 for P, U for J, I for K, O for L,
H for N, and J for M. (Those were the only keystrokes that you got wrong-you
caught yourself before you got much further.) You also never touched the shift
key, so it's all lowercase letters that you care about.
Knowing Java as you do, you decide to write a quick program to ¯x your text.
Write a method fixItUp that takes a string as input and returns a string with
the characters put the way that they ought to have been. See the ¯xItUp method
in the StringWorker class in the bookClassesFinal directory.

```
/**
* Method to f i x up bad t y p ing on a s t r i n g
*/
public s tat ic St r ing f ixI tUp ( St r ing badInput )
{
char [ ] charArray = new char [ badInput . l eng th ( ) ] ;
char currChar ;
// loop through the c h a r a c t e r s in the s t r i n g
for ( int i = 0 ; i < badInput . l eng th ( ) ; i++)
{
currChar = badInput . charAt ( i ) ;
i f ( currChar == ' 7 ' )
charArray [ i ] = 'u ' ;
el se i f ( currChar == ' 8 ' )
charArray [ i ] = ' i ' ;
el se i f ( currChar == ' 9 ' )

el se i f ( currChar == ' 0 ' )
charArray [ i ] = 'p ' ;

charArray [ i ] = ' j ' ;
el se i f ( currChar == ' i ' )
charArray [ i ] = ' k ' ;

charArray [ i ] = ' l ' ;
el se i f ( currChar == 'h ' )
charArray [ i ] = 'n ' ;
el se i f ( currChar == ' j ' )
charArray [ i ] = 'm' ;
el se i f ( currChar == ' y ' )
charArray [ i ] = 'h ' ;
el se i f ( currChar == ' 6 ' )
charArray [ i ] = ' y ' ;
el se
charArray [ i ] = currChar ;
}
return new St r ing ( charArray ) ;
}
