bool.java

这是我学习JAVA时自己的写的代码

//: Bool.java
// Relational and logical operators
import java.util.*;
public class Bool {
public static void main(String[] args) {
Random rand = new Random();
int i = rand.nextInt() % 100;
int j = rand.nextInt() % 100;
prt("i = " + i);
prt("j = " + j);
prt("i > j is " + (i > j));
prt("i < j is " + (i < j));
prt("i >= j is " + (i >= j));
prt("i <= j is " + (i <= j));
prt("i == j is " + (i == j));
prt("i != j is " + (i != j));
// Treating an int as a boolean is
// not legal Java
//! prt("i && j is " + (i && j));
//! prt("i || j is " + (i || j));
//! prt("!i is " + !i);
prt("(i < 10) && (j < 10) is "
+ ((i < 10) && (j < 10)) );
prt("(i < 10) || (j < 10) is "
+ ((i < 10) || (j < 10)) );
}
static void prt(String s) {
System.out.println(s);
}
