You can also convert aStringto aStringBufferby passing theStringinstance into theStringBufferconstructor call: publicstaticvoidmain(String[]args){Stringstr="Hello World!";StringBuffersb=newStringBuffer(str);System.out.println("Variable sb type: "+sb.getClass().getSimpleName());// Variable sb t...
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...

能够看到String.valueOf是通过调用Integer.toString实现的,也难怪他们的效率如此接近。 他们最后都会调用到convertInt函数中: privatestaticStringconvertInt(AbstractStringBuilder sb,inti){booleannegative=false;StringquickResult=null;if(i <0) { negative =true; ...
