this blog post last modified: January 06, 2017, 11:06.

First, Introduction
This article describes how to write a simple input system, you can enter the names of two people, age, and then through the name of the query age.

Second, the experimental platform
System version: Windows7 Home normal version 32-bit operating system.

Four, the experiment Premise 1, before the step of this article, please read the following blog: No
2, before the steps of this article, please implement the following blog:
Temporarily No

v. Basic knowledge

Temporarily No

Vi. Steps of the experiment

1, write code

Import Java.util.Scanner;

public class Inputtest
{public
    static void Main (string[] args)
    {
	String name1;
	int age1;
	String name2;
	int age2;
	String Check_name;

	Initialize Scanner object input
        Scanner input = new Scanner (system.in);
        Scanner input1 = new Scanner (system.in);
        Scanner input2 = new Scanner (system.in);

	Enter name 1
	System.out.println ("Please input name 1:");
	name1 = Input.nextline (); 

	Enter age 1
	System.out.println ("Please input age 1:"); 
	Age1 = Input.nextint ();

	Enter name 1
	System.out.println ("Please input Name 2:"); 
	name2 = Input1.nextline ();

	Enter age 1
	System.out.println ("Please input age 2:"); 
	Age2 = Input1.nextint ();

	Query
	System.out.println ("Please enter the name of the age to be queried:"); 
	Check_name = Input2.nextline ();
	if (Name1.equals (check_name))
	{
		System.out.println ("The age of the person you queried is:" + age1);
	}
	else if (name2.equals (check_name))
	{	
		System.out.println ("The age of the person you queried is:" + age2);
	}
	else
	{
		System.out.println ("This person does not exist.") "); 
	}
    }
}

Pay attention to a few problem points:

1, "Import Java.util.Scanner;" This code must have, otherwise the scanner class in the text cannot be found.

2, each input needs a new scanner class object, otherwise input will not be normal.

3, a.equals (b) is the use of the comparison of two strings.

vii. Results of the experiment

Temporarily No

viii. Results of the experiment

In the experiment, the melon, 27 years old, as well as the idea, 29 years old, and then through the search for the name of the trace, the query to his 29-year-old.

Therefore, a simple input system is realized.
