Ich versuche herauszufinden, wie man doppelte Klasseninformation aus schulinformation entfernen, wenn die folgenden Bedingungen übereinstimmen:

  • Code: Select all

    classInformation.teacherPercentage
    und classInformation.teachInfo.id sind gleich

  • Code: Select all

    classInformation.studentPercentage
    and classInformation.studentInfo.id, classInformation.studentInfo.style, classInformation.studentInfo.graduationYear are the same
JSON:

Code: Select all

{
"schoolInfomration": [
{
"classInformation": [
{
"studentPercentage": 50,
"studentInfo": {
"id": 4,
"style": 3,
"graduationYear": 2028
}
},
{
"teacherPercentage": 50,
"teacherInfo": {
"id": "10019",
"name" : "test2"
}
}
]
},
{
"classInformation": [
{
"studentPercentage": 50,
"studentInfo": {
"id": 4,
"style": 3,
"graduationYear": 2028
}
},
{
"teacherPercentage": 50,
"teacherInfo": {
"id": "10019",
"name" : "test1"
}
}
]
},
{
"classInformation": [
{
"studentPercentage": 50,
"studentInfo": {
"id": 4,
"style": 3,
"graduationYear": 2023
}
},
{
"teacherPercentage": 50,
"teacherInfo": {
"id": "10018",
"name": "test3"
}
}
]
}
]
}
