Java reflection get public field

The java.lang.Class provides the methods to examine the runtime properties of the object including its members and type information. For every type of object, the JVM instantiates an immutable instance of java.lang.Class. Using reflection, we can get the metadata of a class at run time.

The getField() method is used to get public field in java.


package com.codesjava;
public class TestClass {
	private int defaultLength = 10;
	private int defaultWidth = 5;
	public String testField = "codesjava";
	public void drawShape(String color) {
		System.out.println("Rectangle create with following properties: ");
		System.out.println("Length: " + defaultLength);
		System.out.println("Width: " + defaultWidth);

package com.codesjava;
import java.lang.reflect.Field;
public class ReflectionTest {
	public static void main(String args[]){
		try {
			Class c=Class.forName("com.codesjava.TestClass");  
			Field field = c.getField("testField");
		} catch (Exception e) {


public java.lang.String com.codesjava.TestClass.testField
