Boolean class getBoolean() method

  • getBoolean() method is available in java.lang package.
  • getBoolean() method is used to return the system property in boolean values either true or false.
  • getBoolean() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
  • getBoolean() method does not throw an exception at the time of returning system property.

Syntax

public static boolean getBoolean(String sys_prop);

Parameters

  • String sys_prop – represents the string value (system _property) to be parsed.

Return Value

The return type of this method is boolean - it returns the corresponding boolean value that represent the String value.

Note: If the given argument system_property exists and the value is equal to true, it returns true.

Example

// Java program to demonstrate the example 
// of getBoolean(String sys_prop) method of Boolean class

public class GetBooleanOfBooleanClass {
    public static void main(String[] args) {
        String sys_prop1 = "Is Java8 exists";
        String sys_prop2 = "Is C++ not support OOPS";

        // By setting property value by using 
        // setProperty(propertyname , value) method
        System.setProperty(sys_prop1, "true");
        System.setProperty(sys_prop2, "false");

        // Store result in boolean variables
        boolean b1 = Boolean.getBoolean(sys_prop1);
        boolean b2 = Boolean.getBoolean(sys_prop2);

        // Display result
        System.out.println("Boolean.getBoolean(sys_prop1): " + b1);
        System.out.println("Boolean.getBoolean(sys_prop2): " + b2);
    }
}

Output

Boolean.getBoolean(sys_prop1): true
Boolean.getBoolean(sys_prop2): false
