Java中连接字符串

Java中连接字符串
方法：通过“+”操作符和StringBuffer.append()方法来连接字符串，并比较其性能

public class StringConcatenate {
		public static void main(String[] args){
			long staticTime = System.currentTimeMillis();
			System.out.println(staticTime);
			for (int i = 0; i < 5000; i++) {
				String result = "this is"+"trsting the"+"difference"+"between"+"String"+"and"+"StringBuffer";	
			}
			long endTime = System.currentTimeMillis();
			System.out.println(endTime);
			System.out.println("字符串连接"+"-使用+操作符："+(endTime)+"ms");
			long startTime1 = System.currentTimeMillis();
			System.out.println(startTime1);
			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("Sting");
				result.append("and");
				result.append("StringBuffer");
			}
			long endTime1 = System.currentTimeMillis();
			System.out.println(endTime1);
			System.out.println("字符串连接"+"-使用+操作符："+(endTime)+"ms");
		}
}

结果：
