The given snippet will generate an error in the statement — String.out.println(string); as the correct statement for printing is — System.out.println(string);. After this correction is done, the output will be as follows:
Central Madras
Working
| Statement | Remark |
|---|---|
StringBuffer city = new StringBuffer("Madras"); | It creates a StringBuffer objectcity which stores "Madras". |
StringBuffer string = new StringBuffer( ); | It creates an empty StringBuffer object string. |
string.append(new String(city)); | It adds the value of city i.e. "Madras" at the end of the StringBuffer object string. string = " Madras". |
string.insert(0, "Central "); | It modifies StringBuffer object string and adds "Central" at 0 index or beginning. Now, string = "Central Madras". |
System.out.println(string); | It prints "Central Madras". |
