Modifies the value of a static field for a Java object.

Category:	Field reference
Applies to:	Java object

Example

Syntax

object.SETSTATICtypeFIELD("field-name", value);

Arguments

object: specifies the name of a Java object.

type

specifies the type for the Java field. The type can be one of the following values:

BOOLEAN: specifies that the field type is BOOLEAN.

BYTE: specifies that the field type is BYTE.

CHAR: specifies that the field type is CHAR.

DOUBLE: specifies that the field type is DOUBLE.

FLOAT: specifies that the field type is FLOAT.

INT: specifies that the field type is INT.

LONG: specifies that the field type is LONG.

SHORT: specifies that the field type is SHORT.

STRING: specifies that the field type is STRING.

See:Type Issues in SAS Language Reference: Concepts

field-name: specifies the Java field name.

Requirement:The field name must be enclosed in either single or double quotation marks.

value: specifies the value for the field.

Details

Once you instantiate a Java object, you can access and modify its public fields through method calls on the Java object. The SETSTATICtypeFIELD method enables you to modify static fields.

Note: The type argument represents a Java data type. For more information about how Java data types relate to SAS data types, see Type Issues in SAS Language Reference: Concepts.

Comparisons

The SETSTATICtypeFIELD method modifies the value of a static field for a Java object. To modify the value of a non-static field, use the SETtypeFIELD method.

Example: Creating a Java Class with Static Fields

The following example creates a simple class that contains three static fields. The Java object j is instantiated, the field values are set using the SETSTATICtypeFIELD method, and then the field values are retrieved.

/* Java code */
import java.util.*;
import java.lang.*;
public class ttestc
{
   public static double d;
   public static double dm()
   {
      return d;
   }
}

/*  DATA step code */
data _null_;
   dcl javaobj j("ttest");
   length val 8;
   length str $20;
   j.setStaticIntField("i", 100);
   j.setStaticDoubleField("d", 3.14159);
   j.setStaticStringField("s", "abc");
   j.getStaticIntField("i", val);
   put val=;
   j.getStaticDoubleField("d", val);
   put val=;
   j.getStaticStringField("s", str);
   put str=;
run;

The following lines are written to the SAS log:

val=100
val=3.14159
str=abc
