relationaldemo.java

我自己学习JAVA过程中用键盘敲的代码

package jerryhfb;
public class RelationalDemo {

public static void main(String[] args) {



//定义几个数

int i = 37;

int j = 42;

int k = 42;

System.out.println("变量数值...");

System.out.println(" i = " + i);

System.out.println(" j = " + j);

System.out.println(" k = " + k);



//大于

System.out.println("大于...");

System.out.println(" i > j = " + (i > j));	//false

System.out.println(" j > i = " + (j > i)); //true

System.out.println(" k > j = " + (k > j)); //false, they are equal



//大于等于

System.out.println("大于等于...");

System.out.println(" i >= j = " + (i >= j)); //false

System.out.println(" j >= i = " + (j >= i)); //true

System.out.println(" k >= j = " + (k >= j)); //true



//小于

System.out.println("小于...");

System.out.println(" i < j = " + (i < j)); //true

System.out.println(" j < i = " + (j < i)); //false

System.out.println(" k < j = " + (k < j)); //false



//小于等于

System.out.println("小于等于...");

System.out.println(" i <= j = " + (i <= j)); //true

System.out.println(" j <= i = " + (j <= i)); //false

System.out.println(" k <= j = " + (k <= j)); //true



//等于

System.out.println("等于...");

System.out.println(" i == j = " + (i == j)); //false

System.out.println(" k == j = " + (k == j)); //true



//不等于

System.out.println("不等于...");

System.out.println(" i != j = " + (i != j)); //true

System.out.println(" k != j = " + (k != j)); //false



}
