整个方法是作为输出方法的一种,在屏幕上做输出显示,且输出完以后光标下移一行;System.out.print()和这个方法都具有相同作用,不同的是print()方法输出后,光标紧跟在输出语句后,不换行

因为在运算符优先级表中+的运算级大于==,那意味着什么呢?就是说在你题中的运算顺序是先把+两边的字符连接,在用连接起来的整体与str2相比较(就是指判断这个整体与str2是否相同:如果不相同输出false;如果相同,输出true),即:先做 "str1等于str2"+str1 ,运行结果是这样的: str1等于str2hello然后做 str1等于str2hello==str2 ,最终结果是这样的: false而我加了括号的运算顺序是怎样呢?先计算==两边的表达式...

three=one+two;
System.out.println("three=one+two==>"+three);
three += one;
System.out.println("three+=one==>"+three);
three -= one;
System.out.println("three-=one==>"+three);
three *= one;
System.out.println("three=one+two==>"+three);
three += one;
System.out.println("three+=one==>"+three);
three -= one;
System.out.println("three-=one==>"+three);
three *= one;
