 Java Scripting > BeanShell > Enhanced for loop

Enhanced for loop 

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell is a natural scripting language for Java. This requires the library bsh-2.0b4.jar to be in classpath. The following example shows enhanced for loop in beanshell script.

File Name  :  
/BEAN_SHELL001/config/enhanced_for_loop.bsh 
   
int [] array = new int [] { 12};

//Iterate int array
for (i : array) {
  print(i);
}

//Iterate characters of string
for (c : "BTC") {
  print(c);
}

//Iterate student objects
for (std : students) {
  print(std.name + " " + std.age);
}

public class Student {

  private String name;
  private int age;
  private String hobby;

  public Student() {

  public Student(String name, int age, String hobby) {
    super();
    this.name = name;
    this.age = age;
    this.hobby = hobby;
  }

  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public int getAge() {
    return age;
  }
  public void setAge(int age) {
    this.age = age;
  }
  public String getHobby() {
    return hobby;
  }
  public void setHobby(String hobby) {
    this.hobby = hobby;
  }
  
  public boolean isKid() {
    return age < 5;
  }
  
  public String toString() {
    return "Student[name = " + name + ", age = " + age + ", hobby = " + hobby + "]";
  }
}

package com.bethecoder.tutorials.bean_shell;

import java.io.InputStreamReader;
import java.util.Arrays;

import bsh.EvalError;
import bsh.Interpreter;

import com.bethecoder.tutorials.bean_shell.common.Student;

public class EnhancedForLoopTest {

  /**
   @param args
   @throws EvalError 
   */
  public static void main(String[] argsthrows EvalError {
    
    Student student = new Student("Sriram"2"Chess");
    Student student2 = new Student("Sudhakar"29"Painting");
    Student student3 = new Student("Charan"18"Reading books");
    
    Interpreter interpreter = new Interpreter();  
    interpreter.set("students", Arrays.asList(student, student2, student3));
    
    InputStreamReader reader = new InputStreamReader(
        EnhancedForLoopTest.class.getClassLoader()
        .getResourceAsStream("enhanced_for_loop.bsh"));
    
    interpreter.eval(reader);
  }

}
   

It gives the following output,
