I am new to
preparation group. so first hi to all..
iam not absolutely clear about operator precedence .
static boolean a,b,c,d;
public static void main(
d = (a=true) || (b=true) && (c=true);
doubt:&& has higher precedence than || then why || is evaluated first.
suggest me a clear guide/tutorial for operator precedence and associativity.

So the answer to your question goes as below
Evaluate: ((a=true) || ((b=true) && (c=true)));
Evaluate: ((true) || ((b=true) && (c=true))); // a=true is executed
As it knows true || something is always true (short circuited), the control breaks at this step without executing the further statements for b and c
So the result is a=true b=false and c=false

Java Operator Precedence and Associativity Table
What are operator precedence and the order of operand evaluation?
Don't get me started about those stupid
subject: operator precedence
Simple precedence question.
boolean x = (a = true) || (b = true) && (c = true);
Logical operators (&& and ||)
