If statement in java 7
This tutorial describes the if statement in java 7. This is one kind of decision making statement.
There are various way to use if statement with else -
If Statement :
If statement contains one boolean condition and if it satisfied then it executes the if block statements otherwise it jumps out the if block.
Syntax :
if(condition) {
......
......//statements
}
If -Else Statement :
In if-else statement, if statement contains boolean condition and if it the condition is true the if block is executed otherwise the else block is executed.
Syntax :
if(condition) {
......
......//statements
}
else{
........
......//statements
}
Nested Ifs statements :
In java, you can use nested if statements that means you can write if statement inside the if block.
Syntax :
if(condition1) {
if(condition2) {
....//statements
}
......
......//statements
}
Multiple Else-If statements :
In java, you can use multiple if-else statements as well as Else-If statements that means if you want to write if statement inside the else block then you can use else-if statement.
if(condition1) {
......
......//statements
}
else if(condition2){
........
......//statements
}
else{
........
......//statements
}
Example :
package decisionMaking; class IfElseStatement { public static void main(String[] args) { int x = 20, y = 200; int max = 100; if (max > x) { // if statement System.out.println("max is greater than x."); } else if (max > y) { // else if statement System.out.println("max is greater than x and y"); } else { // else statement System.out.println("max is less than x and y"); } } }
Output :
max is greater than x.
