import java.math.BigDecimal;
float mFloat = BigDecimal.valueOf(yourJSONobject.getDouble("double")).floatValue();
Here is what the above code is Doing:
1. It’s getting the double value from the JSON object.
2. It’s converting the double value to a BigDecimal.
3. It’s converting the BigDecimal to a float.
//Assuming that your object is a valid List object, you can use: Collections.singletonList(object) — Returns an immutable list containing only the specified object. List list = Collections.singletonList(object); //If you want it in a specific datatype, use Stream.of(object): List list = Stream.of(object).map(Object::toString).collect(Collectors.toList()) //Similarly, you can change the method in the map to convert to the datatype…
//Send value from HomeActivity val intent = Intent(this@HomeActivity,ProfileActivity::class.java) intent.putExtra(“Username”,”John Doe”) startActivity(intent) //Get values in ProfileActivity val profileName=intent.getStringExtra(“Username”) Here is what the above code is Doing: 1. We are creating an Intent object and passing the current context and the activity class to which we want to navigate. 2. We are putting the value in the…
import java.util.Scanner; // import scanner Scanner myScanner = new Scanner(System.in); // Make scanner obj String inputString = myScanner.nextLine(); // Take whole line boolean inputBoolean = myScanner.nextBoolean(); //Boolean input long inputLong = myScanner.nextLong(); //Interger,long … input Here is what the above code is Doing: 1. We create a new Scanner object called myScanner. 2. We call…
Double.parseDouble(p.replace(‘,’,’.’)) Here is what the above code is Doing: 1. We’re using the map function to apply the function to each element in the list. 2. We’re using the replace function to replace the comma with a dot. 3. We’re using the parseDouble function to convert the string to a double.
@Column(length = 32, columnDefinition = “varchar(32) default ‘UNKNOWN'”) @Enumerated(value = EnumType.STRING) private CommunicationStatus emailCommunicationStatus = CommunicationStatus.UNKNOWN; Here is what the above code is Doing: 1. The @Column annotation is used to specify the column name and length. 2. The @Enumerated annotation is used to specify the type of the enumeration. 3. The @Enumerated annotation can…
int[] a = {1,2,3,4,5}; int[] b = Arrays.copyOf(a, a.length); Here is what the above code is Doing: 1. Create an array of ints called a. 2. Create an array of ints called b. 3. Copy the contents of a into b.
