How to return a boolean method in java?
Solution 1
You're allowed to have more than one return
statement, so it's legal to write
if (some_condition) {
return true;
}
return false;
It's also unnecessary to compare boolean values to true
or false
, so you can write
if (verifyPwd()) {
// do_task
}
Edit: Sometimes you can't return early because there's more work to be done. In that case you can declare a boolean variable and set it appropriately inside the conditional blocks.
boolean success = true;
if (some_condition) {
// Handle the condition.
success = false;
} else if (some_other_condition) {
// Handle the other condition.
success = false;
}
if (another_condition) {
// Handle the third condition.
}
// Do some more critical things.
return success;
Solution 2
try this:
public boolean verifyPwd(){
if (!(pword.equals(pwdRetypePwd.getText()))){
txtaError.setEditable(true);
txtaError.setText("*Password didn't match!");
txtaError.setForeground(Color.red);
txtaError.setEditable(false);
return false;
}
else {
return true;
}
}
if (verifyPwd()==true){
addNewUser();
}
else {
// passwords do not match
System.out.println("password do not match"); }
Solution 3
You can also do this, for readability's sake
boolean passwordVerified=(pword.equals(pwdRetypePwd.getText());
if(!passwordVerified ){
txtaError.setEditable(true);
txtaError.setText("*Password didn't match!");
txtaError.setForeground(Color.red);
txtaError.setEditable(false);
}else{
addNewUser();
}
return passwordVerified;
Solution 4
public boolean verifyPwd(){
if (!(pword.equals(pwdRetypePwd.getText()))){
txtaError.setEditable(true);
txtaError.setText("*Password didn't match!");
txtaError.setForeground(Color.red);
txtaError.setEditable(false);
return false;
}
else {
addNewUser();
return true;
}
}
Solution 5
Best way would be to declare Boolean
variable within the code block and return
it at end of code, like this:
public boolean Test(){
boolean booleanFlag= true;
if (A>B)
{booleanFlag= true;}
else
{booleanFlag = false;}
return booleanFlag;
}
I find this the best way.

I need help on how to return a boolean method in java. This is the sample code:
public boolean verifyPwd(){ if (!(pword.equals(pwdRetypePwd.getText()))){ txtaError.setEditable(true); txtaError.setText("*Password didn't match!"); txtaError.setForeground(Color.red); txtaError.setEditable(false); } else { addNewUser(); } return //what? }
I want the
verifyPwd()
to return a value on either true or false whenever I want to call that method. I want to call that method like this:if (verifyPwd()==true){ //do task } else { //do task }
How to set the value for that method?
