请问是哪里出现了错误？

//先理解数据类型，数据类型要一样，int为整数类型，String为字符串类型，就是: "a"，类似加双引号的，输出为a。

//在此编写你的代码
int a =5;
int b =7;
System.out.println(a+b);
System.out.println(a*b);
}

int a=5 ;
int b=7; System.out.println(a+b); System.out.println(a*b);
String variables are defined within " " but certainly 5 + 7 within the string would be printed as 57 not 12. You could for example write int x = a + b; int y = a * b; anx then print them out.
Change System.out.print to System.out.println because print prints the results in one line and println in a new line
