如何在数组中存储params的值

var paramsArray = [];
paramsArray[0] = "value1";
paramsArray[1] = "value2";
paramsArray[2] = "value3";

$paramsArray = array();
$paramsArray["param1"] = "value1";
$paramsArray["param2"] = "value2";
$paramsArray["param3"] = "value3";

class ParamsObject {
    String paramName;
    String paramValue;
    
    public ParamsObject(String paramName, String paramValue) {
        this.paramName = paramName;
        this.paramValue = paramValue;
    }
}

ParamsObject[] paramsArray = new ParamsObject[3];
paramsArray[0] = new ParamsObject("param1", "value1");
paramsArray[1] = new ParamsObject("param2", "value2");
paramsArray[2] = new ParamsObject("param3", "value3");
