How to optimize string creation?

By using string literals.

Ex:

File: StringPerformance .java

public class StringPerformance {
	public static void main(String[] args) {
		long startTime = System.currentTimeMillis();
 
		for (int i = 0; i < 100000; i++) {
			String str1 = "India";
			String str2= "India";
		}
		long endTime = System.currentTimeMillis();
		System.out.println("Time taken to create literal String : "	+ (endTime - startTime) + " ms");
		long startTime1 = System.currentTimeMillis();
 
		for (int i = 0; i < 100000; i++) {
			String str1 = new String("India");
			String str2 = new String("India");
		}
		long endTime1 = System.currentTimeMillis();
		System.out.println("Time taken to create Object String : " + (endTime1 - startTime1) + " ms");
	}
}

Output:

Time taken to create literal String : 9 ms
Time taken to create Object String : 11 ms

Hence, String creation using literals take less time.
