Java break

description

The use of Java break ends the current cycle .

topic

Use break to end the current loop and calculate the data of 1, 2, 3, 4, 5, but only the sum of the first 3 numbers is required.

Problem solving ideas

1. Define the loop to execute 5 times, and the loop variable from 1 to 5 represents all data.
2. Use if to judge , when the loop reaches 4, use break to end the loop.
3. Output the final result.

Code implementation

public class BreakDemo01 {
    
    
    public static void main(String[] args) {
    
    
        System.out.println("嗨客网(www.haicoder.net)\n");
        
        // 定义一个变量存储结果
        int sum = 0;
        // 运用循环计算
        for(int i = 1; i <= 5; i++){
    
    
            if(i == 4){
    
    
                break;
            }
            sum += i;
        }
        // 打印结果
        System.out.println("1+2+3 结果为：" + sum);
    }
}

The running result is as shown in the figure below:

Here you can see that the loop ends when it is executed for the fourth time.
