Java - Strings and String Handling

Identify the error in this Java code snippet:

String s = "Java Programming";
String part = s.substring(5, 3);
System.out.println(part);

Asubstring() cannot be used on String objects

BMissing semicolon after substring() call

Csubstring() arguments are reversed; start index must be <= end index

DThe variable 'part' is not declared

Step-by-Step Solution

Solution:

Step 1: Check substring() method argument rules
substring(start, end) requires start index less than or equal to end index; here 5 > 3, which is invalid.
Step 2: Confirm other syntax correctness
Semicolons are present, substring() is valid on String, and 'part' is declared properly.
Final Answer:
substring() arguments are reversed; start index must be <= end index -> Option C
Quick Check:
substring(start, end) needs start ≤ end [OK]

Quick Trick: Start index must not be greater than end index in substring() [OK]
