The following are methods for Integer.

• format()

  Returns the integer as a string using the locale of the context user.

• valueOf(stringToInteger)

  Returns an Integer that contains the value of the specified String. As in Java, the String is interpreted as representing a signed decimal integer.

Returns the integer as a string using the locale of the context user.

public String format()

Type: String

public static Integer valueOf(String stringToInteger)

• stringToInteger:

  Type: String

Type: Integer

A TypeException is returned if you attempt to convert a string to an invalid integer.

Converts the specified object to an Integer. Use this method to convert a history tracking field value or an object that represents an Integer value.

public static Integer valueOf(Object fieldValue)

• fieldValue:

  Type: Object

Type: Integer

Use this method with the OldValue or NewValue fields of history sObjects, such as AccountHistory, when the field type corresponds to an Integer type, like a number field.
