学习JAVA第一周，三个数比较大小。

import java.util.Scanner;


public class Main {


public static void main(String[] args) {
// TODO Auto-generated method stub
int x;
int y;
int z;
int max;
Scanner in = new Scanner(System.in );
x=in.nextInt();
y=in.nextInt();
z=in.nextInt();
System.out.println("x="+x+";y="+y+";z="+z);
if(x {
if(y max=z;
}
else{
max=y;
}
}
else{
if(x>z){
max=x;
}
else{
max=z;
}

}
System.out.println("max="+max);
in.close();
}

}
