Differences
Expression1	Expression2	Difference
chars	value	VARIABLE_NAME_MISMATCH
char[]	java.lang.String	VARIABLE_TYPE_MISMATCH
chars	value	VARIABLE_NAME_MISMATCH
char[]	java.lang.String	VARIABLE_TYPE_MISMATCH

Preondition Violations
Type char[] of variable chars does not match with type java.lang.String of variable value Make classes char[] and java.lang.String extend a common superclass
Type char[] of variable chars does not match with type java.lang.String of variable value Make classes char[] and java.lang.String extend a common superclass


for (int i = 0; i < value.length(); i++)

3	char charAt = value.charAt(i);

Preondition Violations
Unmatched statement char charAt=value.charAt(i); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted

char charAt = value.charAt(i);
