Loop end --> Convert StringBuilder or StringBuffer to String Convert StringBuilder or StringBuffer to String --> Output result Output result --> End 通过上面的流程图,我们可以清晰地看到使用循环进行字符串拼接的整个过程。首先初始化一个StringBuilder或StringBuffer对象,然后在循环中不断添加字符串,最后将St...
Or how can I convert StringBuffer to String without compromising the code? public static StringBuffer addFiller (StringBuffer input) { for( int x = 0; x < input.length() - 1; x++) { if(input.substring(x+1, 1).equals(input.substring(x, 1))) { input = input.insert(x+1, "Q"...

和java编译为class的时候会使用StringBuffer 做字符串拼接操作。发现不管是大小项目,甚至到了框架也时常看见+号拼接的情况,虽然高版本的JDK这种编译优化下的影响实际上已经很小了,但是个人还是不太喜欢这种+号拼接的写法,不够优雅。 正确用法 logger.info("Processing trade with id: {} and symbol : {} ", id...
特别是String对象的使用,出现字符串连接时应该使用StringBuilder/StringBuffer代替。由于Java虚拟机不仅要花时间生成对象,以后可能还需要花时间对这些对象进行垃圾回收和处理,因此,生成过多的对象将会给程序的性能带来很大的影响。 3、尽可能使用局部变量 调用方法时传递的参数以及在调用中创建的临时变量都保存在栈中,速度较...
