Java exercises 11.1
1. Define a method to determine whether two numbers are the same
package com.shangjiti.aoian;
import java.util.Scanner;
public class No4 {
public static void main(String[] args) {
System.out.println("请输入两个数:");
Scanner sc=new Scanner(System.in);
int num1=sc.nextInt();
int num2=sc.nextInt();
if(isSame(num1,num2)==true)
System.out.println("相同");
else
System.out.println("不同");
//boolean isSame=isSame(num1,num2); 写法二
//System.out.println(isSame);
}
public static boolean isSame(int num1,int num2) {
if(num1==num2)
return true;
else
return false;
}
}
2. Define a method to find the larger number of two integers
package com.shangjiti.aoian;
import java.util.Scanner;
public class No3 {
public static void main(String[] args) {
System.out.println("请输入两个整数:");
Scanner sc=new Scanner(System.in);
int i=sc.nextInt();
int j=sc.nextInt();
int k=n(i,j);
System.out.println(k);
}
public static int n(int num1, int num2) {
int result;
if (num1 > num2)
result = num1;
else
result = num2;
return result;
}
}
3. Define a method to print the ten numbers 0-9
package com.shangjiti.aoian;
public class No1 {
public static void main(String[] args) {
num();
}
public static void num() {
for(int i=0;i<10;i++)
System.out.print(i+" ");
}
}
4. Extend the above program, you can customize printing from several to several integers
package com.shangjiti.aoian;
import java.util.Scanner;
public class No2 {
public static void main(String[] args) {
System.out.println("请输入两个整数:");
Scanner sc=new Scanner(System.in);
int begin=sc.nextInt();
int end=sc.nextInt();
printFw(begin,end);
}
public static void printFw(int b,int e) {
for(int i=b;i<=e;i++)
System.out.print(i+" ");
}
}
