Pass a variable from a method to another

Question

Hello,
how is it possible to use, in a method, a variable instanciated in another method? None of them is a constructor. I saw many examples in the tutorials with constructors, but there it's different...
This is a piece of my program:
String string_;
String other;
public String getName()throws IOException{
     byte[] input = new byte[50];
     System.out.println("give string_");
     System.in.read(input);
     String other = new String(input);
     other = other.trim();
     System.out.println("other = "+other);
     return other ;
public String Native( ){
     System.out.println("other in Native() = "+ other);
     string_ = other;
     return string_;
When I run it I get the answer:
other in Native()= null
So the value I gave to other didn't pass from getName() to Native()...
How can I do that?

Your code:
  String string_;
  String other;
  public String getName()throws IOException {
    byte[] input = new byte[50];
    System.out.println("give string_");
    System.in.read(input);
    String other = new String(input);
    other = other.trim();
    System.out.println("other = "+other);
    return other;
  public String Native() {
    System.out.println("other in Native() = "+ other);
    string_ = other;
    return string_;
  }change to:
  String string_;
  String other;
  public String getName()throws IOException {
    byte[] input = new byte[50];
    System.out.println("give string_");
    System.in.read(input);
    String other = new String(input);
    other = other.trim();
    System.out.println("other = "+other);
    return other;
  public String Native(String another_other) {
    System.out.println("other in Native() = "+ other);
    another_other+="\tanother_other";
    string_ = another_other;
    return string_;
  }You'll see the change. You want to pass somthing into Native specifically and change it locally, and see the difference, right? Well this is the way you pass something in.
