我想输出这些逻辑运算的值，但是eclipse显示有错
import java.util.Scanner;
public class Application3_1 {
public static void main (String args[]){
Scanner reader=new Scanner(System.in);
int x,y,z;
System.out.printf("输入变量的值:");
x=reader.nextInt();
y=reader.nextInt();
z=reader.nextInt();
System.out.println("x+y&&z-y");
System.out.println("x<y<z||x>y>z");
System.out.println("x-x&&y-y||z-z");
System.out.println("(x-x)&&y-y");
}
}
