我们可以让JVM抛出我们自己的用户定义异常吗？(Can we make the JVM to throw our own user defined exception?)

 myData看起来格式不正确。 在前一个括号之后有一个额外的逗号： 
 
},
 
 }]; 
 
 您可以遍历对象属性： 
 
var data = [];
for (var i = 0; i < mydata.length; i++) {       //looping through data received
    var obj = mydata[i];      //current obj in loop
    for(var key in obj){
      var newObj = {      //creating new obj with same structure as the 'data' that works
          name: obj[key].name,
          y: obj[key].subhere.subhere1,
          id: i   

      };
    data.push(newObj);      //pushing each object
  }
}

myData doesn't look correctly formatted. It has an extra comma after the bracket before last:
 
},
 
}];
 
You can loop through your object properties:
 
var data = [];
for (var i = 0; i < mydata.length; i++) {       //looping through data received
    var obj = mydata[i];      //current obj in loop
    for(var key in obj){
      var newObj = {      //creating new obj with same structure as the 'data' that works
          name: obj[key].name,
          y: obj[key].subhere.subhere1,
          id: i   

      };
    data.push(newObj);      //pushing each object
  }
}
