There's a code snippet in JavaScript that I'm not familiar with, but I need to pass this information to one of my Java methods.
example.setChoices([{ value : 'One', label : 'Label One', disabled : true }], 'value', 'label', false);
I've been researching on w3schools and other JavaScript sources, but it doesn't seem like a simple map.
I'm struggling to understand what kind of Map this would be in Java.
My objective is to send this data to my Java method.
Although unconventional, it is possible to create a <Object,Object> map in JavaScript due to its flexibility with mixed datatypes.
One approach could be converting boolean values to strings for consistency within the "raw object map."
Map<Object, Object> test = new HashMap<>();
test.put("firstString", "first");
test.put("secondString", "second");
test.put("thirdBool", true);
In regards to the provided code:
Map<Object, Object> test = new HashMap<>();
test.put("value", "value");
test.put("label", "label");
test.put("disabled", false);
For custom classes, it's recommended to define a specific class structure like this:
class FooObject{
private String value;
private String label;
private boolean disabled;
FooObject(String value,String label,boolean disabled){
this.value=value;
this.label=label;
this.disabled=disabled;
}
public String getValue(){
return this.value;
}
public String getLabel(){
return this.label;
}
public boolean isDisabled(){
return this.disabled;
}
}
This custom class can then be used in a map as shown below:
Map<Integer, FooObject> test = new HashMap<>();
test.put(0,new FooObject("first","1 label",false));
//Accessing parameters
test.get(0).isDisabled();
test.get(0).getValue();
test.get(0).getLabel();
While Java does not support default values, you can override constructors to simulate defaults:
FooObject(String value,String label,boolean disabled){
this.value=value;
this.label=label;
this.disabled=disabled;
}
FooObject(String value,String label){
this.value=value;
this.label=label;
//default value
this.disabled=true;
}
