class IF
{
    public static void main(String args[])
    {  
        int x,y;
        x=10;
        y=20;
        if(x!=y);{
        if(x>y);
            System .out.println("x的值比y的值大。");
        else
            System .out.println("x的值比y的值大。");
        } 
        else
            System.out.println("x的值与y的值相等。");
    }}
