训练编程逻辑的练习列表

我给社区中的每个人留下了一份训练编程逻辑的练习清单。
（我为每一个留下了我的解决方案，使用java语言）

练习

1 - 创建一个算法，读取 a、b、c 的值，然后在屏幕上打印 a 和 b 之间的总和，并显示总和是否小于 c。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        system.out.println("write a value of a:");
        scanner integerscanner = new scanner(system.in);
        int a = integer.parseint(integerscanner.next());
        system.out.println("write a value of b:");
        int b = integer.parseint(integerscanner.next());
        system.out.println("write a value of c:");
        int c =  integer.parseint(integerscanner.next());
        int sum = a + b ;

        if (sum <= c){
            system.out.println("the result of value a + b is: " + sum + ";\nthe sum of a + b is less or equal value c");
        }
        else{
            system.out.println("the result of value a + b is: " + sum + ";\nthe sum of a + b dont is less or equal value c");
        }
    }
}

2 - 创建一个算法来接收任何数字并在屏幕上打印，无论该数字是偶数还是奇数，正数还是负数。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        system.out.println("write a number:");
        scanner integerscanner = new scanner(system.in);
        int number = integer.parseint(integerscanner.next());
        if (number >=0){
            if (number % 2 == 0){
                system.out.println("the number " + number + " is 'even' = par and positive");
            } else system.out.println("the number " + number + " is 'odd' = impar and positive");
        } else {
            if (number % 2 == 0){
                system.out.println("the number " + number + " is 'even' = par and negative");
            } else
                system.out.println("the number " + number + " is 'odd' = impar and negative");

        }
    }
}

3 - 制作一个算法，读取两个整数值a和b，如果a和b的值相等，则必须将这两个值相加，

否则，您必须将 a 乘以 b。在任何计算结束时，您必须将结果分配给变量 c 并且

在屏幕上打印您的值。

package org.example;
import java.util.scanner;
public class main {

    public static void main(string[] args) {
        system.out.println("write your first value:");
        scanner integerscanner = new scanner(system.in);
        int a = integerscanner.nextint();
        system.out.println("write your second value:");
        int b = integerscanner.nextint();
        int c;
        if (a == b){
            c = a + b;
            system.out.println("the sum off a + b is: " + c);
        } else {
            c = (a * b);
            system.out.println("the multiple of a x b is: " + c);
        }
    }
}

4 - 创建一个接收整数并在屏幕上打印其前任和后继的算法。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        scanner integerscanner = new scanner(system.in);
        system.out.println("write your number: ");
        int number = integerscanner.nextint();
        int nextnumber = number + 1;
        int previousnumber = number - 1;
        system.out.println("the next number is: " + nextnumber);
        system.out.println("the previous number is: " + previousnumber);
    }
}

5 - 创建一个算法，读取最低工资的值和用户工资的值，计算出这个最低工资是多少

用户获胜并在屏幕上打印结果。（最低工资基数为 1,293.20 雷亚尔）。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        scanner doublescanner = new scanner(system.in);
        system.out.println("write your salario: ");
        double salariomin = 1293.20;
        double salario = doublescanner.nextdouble();
        double total = salario / salariomin;
        system.out.printf("the salario is: %.2fx o salario min" , total);
    }
}

6 - 创建一个算法，读取任何值并将其打印在屏幕上，并调整 5%。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        scanner scanner = new scanner(system.in);
        system.out.print("write a value: ");
        double a = scanner.nextdouble();
        double total = a *.05;
        double result = a + total;
        system.out.printf("the value with 5%% increase is: %.2f" , result);
    }
}

7 - 制作一个读取两个布尔（逻辑）值并确定它们是 true 还是 false 的算法。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
    scanner scanner = new scanner(system.in);
    system.out.print("write a boolean value: ");
    boolean value1 = scanner.nextboolean();
    system.out.print("write other boolean value: ");
    boolean value2 = scanner.nextboolean();

    if (value1 && value2){
        system.out.println("values are true");
    } else if (!value1 && !value2){
        system.out.println("values are false");
    } else {
        system.out.println("value are different");
    }
    }
}

8 - 制作一个算法，读取三个不同的整数值并按降序在屏幕上打印这些值。

package org.example;
import java.util.scanner;
import java.util.arrays;
public class main {
    public static void main(string[] args) {
        scanner scanner = new scanner(system.in);
        system.out.println("write your first value");
        int value1 = scanner.nextint();
        system.out.println("write your second value");
        int value2 = scanner.nextint();
        system.out.println("write your third value");
        int value3 = scanner.nextint();
        int[] values = {value1, value2, value3};
        arrays.sort(values);

        system.out.println("values in descending order:");
        for (int i = values.length - 1; i >= 0; i--) {
            system.out.print(values[i] + " ");
        }
    }
}

9 - 创建一个算法来计算一个人的 bmi（身体质量指数），读取他们的体重和身高并在屏幕上打印他们的状况

根据下表：

bmi公式=体重/（身高）²

bmi状况表

18.5岁以下|体重不足

18.6 至 24.9 之间 |理想体重（恭喜）

25.0 至 29.9 之间 |有点超重

30.0 至 34.9 之间 | i级肥胖

35.0 至 39.9 之间 |肥胖ii级（重度）

大于或等于40 |肥胖iii级（病态）

em breve

10 - 创建一个算法，读取学生获得的三个成绩，并在屏幕上打印成绩的平均值。

package org.example;
import java.util.scanner;
public class main {
    public static void main(string[] args) {
        system.out.println("write your first grade");
        scanner integerscanner = new scanner(system.in);
        int grade = integer.parseint(integerscanner.next());
        system.out.println("write your second grade");
        int grade2 = integer.parseint(integerscanner.next());
        system.out.println("write your third grade");
        int grade3 = integer.parseint(integerscanner.next());
        int sum = grade3 + grade + grade2;
        float result = (float)sum /3;
        system.out.printf("your average grade is: %.1f" , result);
    }
}

11 - 创建一个算法，读取学生获得的四个成绩，计算获得的成绩的平均值，在屏幕上打印学生的姓名，然后

学生是否通过或未通过。要使学生被视为获得批准，他们的最终平均分必须大于或等于 7。
