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.输出自增自减
*/
import java.util.Scanner;
public class Z
{
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.输出结果是什么?
*/
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.输出结果是什么?
*/
public class ThreeP
{
public static void main(String[] args)
{
int x=0,y;
y=x>1?100:200;
System.out.println("y="+y);
}
}
import java.util.Scanner;
public class Threeb
{
public static void main(String[] args)
{
Scanner input=new Scanner(System.in);
System.out.print("输入三个数:");
int a=input.nextInt();
int b=input.nextInt();
int c=input.nextInt();
a=a>b?a:b;
c=a>c?a:c;
System.out.println(c);
}
}
6.用三元运算符做联系
*/
{
public static void main(String[] args)
{
Scanner input=new Scanner(System.in);
int month;
System.out.println("Enter the month ");
month=input.nextInt();
if(month>=3&&month<=5){
System.out.println("This month is spring");
}else if(month>=6&&month<=8){
System.out.println("This month is summer");
}else if(month>=9&&month<=11){
System.out.println("This month is autumn");
}else if(month==12){
System.out.println("This month is winter");
}else if(month>=1&&month<=2){
System.out.println("This month is winter");
}else{
System.out.println("Error!");
}
}
}
7.使用判断语句,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-叶子发芽了!");
if(a>=6&&a<=8)
System.out.println("夏-好多叶子!");
if(a>=9&&a<=11)
System.out.println("秋-叶子黄了!");
if(a>=12&&a<=2)
System.out.println("冬-树秃顶了!");cls
}
}
8.使用循环语句,分析程序的输出结果
*/
public class Dp
{
public static void main(String[] args)
{
int x=1;
do
{
System.out.println("x="+x);
x++;
}while(x<1);
}
}
