JAVA程序运算符练习

public class OK 
{
    
    public static void main(String[] args)
    {
        
        System.out.println("ok");
        
        int ok = 123;
        
        System.out.println(ok);
        
        System.out.println(" b = " + ok);
        
        System.out.println("z = " + ok++);
        
        System.out.println("z = " + ++ok);
        
        System.out.println("z = " + ok--);
        
        System.out.println("z = " + --ok);
        
        int a = ++ok;
        
        System.out.println("z = "+ a );
        
        int  m = 1 , n = 2, o = 3 ,p = 4;
        
        System.out.println("ok = "+  ((m + n) *o /(p - o) + p) );
        
        System.out.println("ok = "+  (m + n) *o /(p - o) + p );
        
        System.out.println("ok = "+  p % n );
        
        
        System.out.println("ok = " +( m > n));
        
        System.out.println("ok = " + (p >= p));
        
        System.out.println("ok = " + (p != p));
        
        System.out.println("ok = " +((p > m )&&(p < m)));
        
        System.out.println("ok = " +((p > m )||(p < m)));
        
        boolean OK = (p != p) && (n < o);
        
        System.out.println(OK );
        
        boolean Ok = (p != p) || (n < o);
        
        System.out.println(Ok );
        
        
        //p *= ok;
        
        System.out.println(p);
        
        System.out.println(p * ok);
        
        System.out.println("p =" + p * ok  );
        
        System.out.println("p =" + p * ok + 1 );
        
        System.out.println( p * ok + 1 );
        
        String jj = p > m ? "yes":"no";
        
        System.out.println(jj );
        
        
        
        String gg ="girl" ,bb ="boy";
        
        if (m > n)
            
        { System.out.println( gg );}
        
        else System.out.println(bb );
        
        String GG = m > n?"girl":"boy";
        
        System.out.println(GG);

输出结果为：

ok
123
 b = 123
z = 123
z = 125
z = 125
z = 123
z = 124
ok = 13
ok = 94
ok = 0
ok = false
ok = true
ok = false
ok = false
ok = true
false
true
4

p =496
p =4961
497
yes
boy
