我遇到错误你能告诉我这个文件中的错误在哪里吗?
public class IfSample {
public static void main(String[] args) {
int x,y;
x=10;
y=20;
if(x<y) System.out.println(“x is less than y”);
x=x*2;
if(x==y) System.out.println(“x now equal to y”);
x=x*2;
if(x>y) System.out.println(“x is greater than y”);
// this won’t display anything.
if(x==y) System.out.println(“you won’t see this”);
}
}

您正在使用这些引号“”
。这就是你得到错误的原因。使用字符串的标准双引号。
if (x < y)
System.out.println("x is less than y"); // standard double quotes
x = x * 2;
if (x == y)
System.out.println("x now equal to y");
x = x * 2;
if (x > y)
System.out.println("x is greater than y");
// this won’t display anything.
if (x == y)
System.out.println("you won’t see this");
