1.输出的结果是什么?
import java.util.Scanner;
public class Prs
{
public static void main(String[] args)
{
System.out.println("5+5="+5+5);
}
}
2.算出输出的结果(自增自减)
public class Increase
{
public static void main(String[] args)
{
int a=3,b;
b=a++;
System.out.println("a="+a+",b="+b);
}
}
3.算出结果
public class Shortp
{
ublic static void main(String[] args)
{
short s=3;
s+=4;
System.out.println("s="+s);
}
}
4.算出结果
public class LogicalRelationship
{
public static void main(String[] args)
{
System.out.println(6&3);
System.out.println(6|3);
System.out.println(6^3);
System.out.println(3<<2);
System.out.println(3>>1);
}
}
5.算出结果
import java.util.Scanner;
public class K {
public static void main(String[] args) {
int x=0,y;
y=x>1?100:200;
sop("y="+y);
}
}
然后算出较大的数字
public class Z
{
public static void main (String[] args){
int a=1,b=0,max;
max=a>b?a:b;
System.out.println("max="+a);
}
}
最后输出最大的数字
public class Q
{
public static void main (String[] args){
int a=1,b=0,c=3,max;
max=a>b?a:b;
max=c>max?c:max;
System.out.println("max="+c);
}
}
6.使用判断语句,根据数字,输出对应的中文是星期几
import java.util.Scanner;
public class WeekP
{
public static void main(String[] args)
{
Scanner input=new Scanner(System.in);
System.out.print("请输入一个1-7之间的数:
");
int weekday=input.nextInt();
if(weekday==1)
System.out.println("周一");
if(weekday==2)
System.out.println("周二");
if(weekday==3)
System.out.println("周三");
if(weekday==4)
System.out.println("周四");
if(weekday==5)
System.out.println("周五");
if(weekday==6)
System.out.println("周六");
if(weekday==7)
System.out.println("周日");
}
}
7
用判断语句,根据数字,输出对应季节
import java.util.Scanner;
public class SwitchP
{
public static void main(String[] args)
{
Scanner input=new Scanner(System.in);
System.out.print("输入一个月份:");
int a=input.nextInt();
if(a>=3&&a<=5)
System.out.println("春");
if(a>=6&&a<=8)
System.out.println("夏");
if(a>=9&&a<=11)
System.out.println("秋");
if(a>=12&&a<=2)
System.out.println("冬");cls
}
}
8.
使用循环语句,分析程序的结果
public class Dp
{
public static void main(String[] args)
{
int x=1;
do
{
System.out.println("x="+x);
x++;
}
while(x<1);
}
}
