3 个数字中的最大值答案

【问题标题】：Highest Value among 3 Numbers3 个数字中的最大值
【发布时间】：2020-04-08 10:03:26
【问题描述】：

问题陈述：SRV 学院希望认可本学年成功获得最多实习机会的院系。参与招聘的部门有CSE、ECE、MECH。帮助学院找到获得最大展示位置的部门。检查示例快照中给出的所有可能输出

注意：如果任何输入为负，则输出应为“输入无效”。如果所有部门的职位数量相同，则输出应为“没有一个部门获得最高职位”。

示例输入 1：

Enter the no of students placed in CSE:90
Enter the no of students placed in ECE:45
Enter the no of students placed in MECH:70
Sample Output 1:
Highest placement
CSE

示例输入 2：

Enter the no of students placed in CSE:55
Enter the no of students placed in ECE:85
Enter the no of students placed in MECH:85
Sample Output 2:
Highest placement
ECE
MECH

示例输入 3：

Enter the no of students placed in CSE:0
Enter the no of students placed in ECE:0
Enter the no of students placed in MECH:0
Sample Output 3:
None of the department has got the highest placement

示例输入 4：

Enter the no of students placed in CSE:10
Enter the no of students placed in ECE:-50
Enter the no of students placed in MECH:40
Sample Output 3:
Input is Invalid

我能够提出一个基本上通过所有可见条件的代码，但未能测试一个。不太确定我哪里出错了。

我完全同意下面的代码效率不高

import java.util.*;
class Placement{
public static void main(String[] args) {
int x,y ,z ;
scanner sc= new Scanner(System.in) ;
System.out.printIn( "Enter the no of students placed in CSE: " );
x=sc.nextInt( );
System.out.printIn("Enter the no of students placed in ECE:" );
y=sc.nextInt( ) ;
System.out.println("Enter the no of students placed in MECH:" );
z=sc.nextInt( ) ;
if(x==z && x==y && y==z){   
System.out.printIn("None of the department has got the highest placement" ) ;
}
else if(x<0 || y<0 || z<0){
System.out.printIn("Input is Invalid" ) ;
}
else{
System.out.println( "Highest placement" );
if(x>=z && x>=z){
if(x==y){
System.out.printIn( "CSE" );
System.out.printIn("ISE" );
}
else if(x==z) {
System.out.printIn("CSE" ) ;
System.out.printIn( "MECH" ) ;
}
else{
System.out.println("CSE" );
}
}
else if(y>=z){
{
if(y==z){
System.out.printIn( "ECE" );
System.out.printIn( "MECH" ) ;
}
else{
System.out.println("ECE" ) ;
}
else{
System.out.printIn( "MECH" ) ;
}
}
}

输出：

Proposed grade: 85. 71 / 100

【问题讨论】：

请在问题本身中包含所有代码和输出
问题是我正在编码的平台不允许我复制或粘贴代码
@Cruncher 我已经通过取出图像添加了代码。财政年度
抱歉，我通过添加代码图像让问题不清楚，我能够从图像中提取文本并添加代码 sn-p 以及获得的输出。
您发布的代码将无法编译：它有System.out.printIn（最后一个字符之前是大写i，而不是小写L）。在单个 if 语句之后还有 2 个 else 块。

很好地找出了错误，不是有效的答案，但得到了它的工作。

import java.util.*;
class Placement{
public static void main(String[ ] args){
int a, b, c;
Scanner sc= new Scanner(System. in) ;
System.out.println("Enter the no of students placed in CSE:");
a=sc.nextInt();
System.out.println("Enter the no of students placed in ECE:");
b=sc.nextInt();
System.out.println("Enter the no of students placed in MECH:");
c=sc.nextInt();
if (a>b && a>c){
System.out.println("Highest placement" ) ;
System.out.println("CSE");
}
else if(a<0 || b<0 || c<0){
System.out.println("Input is Invalid");
}
else if(b>a && b>c){
System.out.println("Highest placement") ;
System.out.println("ECE") ;
}
else if(c>a && c>b){
System.out.println("Highest placement") ;
System.out.println( "MECH" ) ;
}
else if(a==b && b==c && c==a){
System.out.println( "None of the department has got the highest placement" ) ;
}
else if(a==b){
System.out.println("Highest placement");
System.out.println("CSE");
System.out.println("ECE");
}
else if(a==c){
System.out.println("Highest placement");
System.out.println("CSE") ;

}
else{
System.out.println("Highest placement");
System.out.println("ECE") ;
System.out.println("MECH") ;
}
}
}

【解决方案2】：

唯一的错误是您在 a==b 条件下输入了 ICE 而不是 ECE

    }
}

这将完美运行。
