Unreachable Statement with Break
break, java, switch-statement
Solution
If you put a `return`, then the function returns before the `break` is executed and therefore the `break` will never be reached.
Instead you could use a variable that you set to a desired value and after the switch return that. Or just get rid of the `break` statements.
Problem
So I had a previous question but realized I posted the wrong offending code. I've marked the offending statements below. What I am trying to do is set the precedence for each of the operators with that switch statement. Maybe someone could point me in the right direction. Just as a note, I AM running JAVA 7 so String Switch will work. Code opType.java ``` import java.io.*; public final class opType { public static opType ADD = new opType( "Add" ); public static opType SUB = new opType( "Sub" ); public static opType MULT = new opType( "Mult" ); public static opType DIV = new opType( "Div" ); public static opType MOD = new opType( "Mod" ); public static opType LPAR = new opType( "LParen" ); public static opType RPAR = new opType( "RParen" ); protected String name; private opType( String n ) { name = n; } public String getName() { return name; } ``` Operator.java ``` public class Operator extends Token { protected opType val; public boolean isOperator() { return true; } public boolean isOperand() { return false; } protected int getPrec() { switch(val.getName()) { case "LParen": { return 0; break; //unreachable } case "RParen": { return 0; break; //unreachable } case "Mult": { return 1; break; //unreachable } case "Div": { return 1; break; //unreachable } case "Mod": { return 1; break; //unreachable } case "Add": { return 2; break; //unreachable } case "Sub": { return 2; break; //unreachable } } return 0; } public static int compare( Operator a, Operator b ) { if( a.getPrec() == b.getPrec() ) return 0; else if( a.getPrec() < b.getPrec() ) return -1; else return 1; } public opType getVal() { return val; } public Operator( opType v ) { val = v; } } ```
