Java编程示例

英尺与米的单位换算

换算公式：（英尺+英寸/12）*0.3084=米

package main;import java.util.Scanner;public class main {public static void main(String[] args) {// TODO Auto-generated method stubScanner in = new Scanner(System.in);int foot;int inch;System.out.print("请输入英尺：");foot=in.nextInt();System.out.print("请输入英寸：");inch=in.nextInt();System.out.print(foot+"英尺"+inch+"英寸"+"="+((foot+inch/12.0)*0.3048)+"米");}}

5英尺7英寸=1.7018米

把1.7018米转换为170厘米：

(int)(meter*100)

(int) 用于把它后面的数（可以是浮点数）转换为整数。

判断三个数的大小

package main;import java.util.Scanner;public class main {public static void main(String[] args) {// TODO Auto-generated method stubScanner in = new Scanner(System.in);int x;int y;int z;int max;x=in.nextInt();y=in.nextInt();z=in.nextInt();if (x>y){if(x>z){max=x;}max=z;}else{if(y>z){max=y;}max=z;}System.out.println(max);}}
