Program:
/* ............... START ............... */
public class JavaStringConcatenationExample {
public static void main(String[] args) {
long startTime = System.currentTimeMillis();
for (int i = 0; i < 5000; i++) {
String result = "This is" + "testing the" + "difference" + "between" + "String" + "and" + "StringBuffer";
}
long endTime = System.currentTimeMillis();
System.out
.println("Time taken for string" + "concatenation using + operator : " + (endTime - startTime) + " ms");
long startTime1 = System.currentTimeMillis();
for (int i = 0; i < 5000; i++) {
StringBuffer result = new StringBuffer();
result.append("This is");
result.append("testing the");
result.append("difference");
result.append("between");
result.append("String");
result.append("and");
result.append("StringBuffer");
}
long endTime1 = System.currentTimeMillis();
System.out.println(
"Time taken for String concatenation" + "using StringBuffer : " + (endTime1 - startTime1) + " ms");
}
}
/* ............... END ............... */
Output
Time taken for stringconcatenation using + operator : 0 ms
Time taken for String concatenationusing StringBuffer : 13 ms
Notes:
-
Example shows performance of concatenation by using "+" operator and StringBuffer.append() method.
