Java Reflection - Field.getFloat() Examples

Class:

java.lang.reflect.Field

Method:

public float getFloat(Object obj)
               throws IllegalArgumentException,
                      IllegalAccessException

Gets the value of a static or instance field of type float or of another primitive type convertible to type float via a widening conversion.

Examples

package com.logicbig.example.field;

import java.lang.reflect.Field;

public class GetFloatExample {
    private float aFloat = 1.3f;
    private int anInt = 2;
    private static float aStaticFloat = 2.3f;

    public static void main(String... args) throws NoSuchFieldException, IllegalAccessException {
        Class<GetFloatExample> c = GetFloatExample.class;
        GetFloatExample instance = new GetFloatExample();

        //instance field
        Field field = c.getDeclaredField("aFloat");
        float f = field.getFloat(instance);
        System.out.println(f);

        //type conversion
        Field field2 = c.getDeclaredField("anInt");
        float f2 = field2.getFloat(instance);
        System.out.println(f2);

        //static field
        Field field3 = c.getDeclaredField("aStaticFloat");
        float f3 = field3.getFloat(null);
        System.out.println(f3);
    }
}
