java - android java 字符串操作

Question

此 PHP 代码的等效 Java 是什么？

//print string plus/with variable     
$mystring = "this is string " .$string

//print sum one + two
$count = $one + $two

//print sum one*two
$count = $one * $two

Answer 1

应该是这样的:

String mystring= "this is string " + string; // here `string` is aloso  String  object

/*
* if count ,one and two all of them are int
*/
int count = one + two;

int count = one * two;

但我建议在开始 android 之前先学习 java 基础知识。正如您所了解的 php，学习 java 语法不会花费很长时间。
