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
496
p =496
p =4961
497
yes
boy
boy
